Abstract

The sauropod of El Oterillo II is a specimen that was excavated from the Castrillo de la Reina Formation (Burgos, Spain), late Barremian–early Aptian, in the 2000s but initially remained undescribed. A tooth and elements of the axial skeleton, and the scapular and pelvic girdle, represent it. It is one of the most complete titanosauriform sauropods from the Early Cretaceous of Europe and presents an opportunity to deepen our understanding of the radiation of this clade in the Early Cretaceous and study the paleobiogeographical relationships of Iberia with Gondwana and with other parts of Laurasia. The late Barremian–early Aptian is the time interval in the Cretaceous with the greatest diversity of sauropod taxa described in Iberia: two titanosauriforms, Tastavinsaurus and Europatitan; and a rebbachisaurid, Demandasaurus. The new sauropod Europatitan eastwoodi n. gen. n. sp. presents a series of autapomorphic characters in the presacral vertebrae and scapula that distinguish it from the other sauropods of the Early Cretaceous of Iberia. Our phylogenetic study locates Europatitan as the basalmost member of the Somphospondyli, clearly differentiated from other clades such as Brachiosauridae and Titanosauria, and distantly related to the contemporaneous Tastavinsaurus. Europatitan could be a representative of a Eurogondwanan fauna like Demandasaurus, the other sauropod described from the Castrillo de la Reina Formation. The presence of a sauropod fauna with marked Gondwananan affinities in the Aptian of Iberia reinforces the idea of faunal exchanges between this continental masses during the Early Cretaceous. Further specimens and more detailed analysis are needed to elucidate if this Aptian fauna is caused by the presence of previously unnoticed Aptian land bridges, or it represents a relict fauna from an earlier dispersal event.

[Paleontology • 2017] Matheronodon provincialis • Extreme Tooth Enlargement in A New Late Cretaceous Rhabdodontid Dinosaur from Southern France ---ScRaBBlE

  Matheronodon provincialis

Abstract
Rhabdodontidae is a successful clade of ornithopod dinosaurs, characteristic of Late Cretaceous continental faunas in Europe. A new rhabdodontid from the late Campanian, of southern France, Matheronodon provincialis gen. et sp. nov., is characterized by the extreme enlargement of both its maxillary and dentary teeth, correlated to a drastic reduction in the number of maxillary teeth (4 per generation in MMS/VBN-02-102). The interalveolar septa on the maxilla are alternately present or resorbed ventrally so as to be able to lodge such enlarged teeth. The rhabdodontid dentition and masticatory apparatus were adapted for producing a strict and powerful shearing action, resembling a pair of scissors. With their relatively simple dentition, contrasting with the sophisticated dental batteries in contemporary hadrosaurids, Matheronodon and other rhabdodontids are tentatively interpreted as specialized consumers of tough plant parts rich in sclerenchyma fibers, such as Sabalites and Pandanites.

Abstract

Background

Archaeopteryx is an iconic fossil that has long been pivotal for our understanding of the origin of birds. Remains of this important taxon have only been found in the Late Jurassic lithographic limestones of Bavaria, Germany. Twelve skeletal specimens are reported so far. Archaeopteryx was long the only pre-Cretaceous paravian theropod known, but recent discoveries from the Tiaojishan Formation, China, yielded a remarkable diversity of this clade, including the possibly oldest and most basal known clade of avialan, here named Anchiornithidae. However, Archaeopteryx remains the only Jurassic paravian theropod based on diagnostic material reported outside China.

Results

Re-examination of the incomplete Haarlem Archaeopteryx specimen did not find any diagnostic features of this genus. In contrast, the specimen markedly differs in proportions from other Archaeopteryx specimens and shares two distinct characters with anchiornithids. Phylogenetic analysis confirms it as the first anchiornithid recorded outside the Tiaojushan Formation of China, for which the new generic name Ostromia is proposed here.

Conclusions

In combination with a biogeographic analysis of coelurosaurian theropods and palaeogeographic and stratigraphic data, our results indicate an explosive radiation of maniraptoran coelurosaurs probably in isolation in eastern Asia in the late Middle Jurassic and a rapid, at least Laurasian dispersal of the different subclades in the Late Jurassic. Small body size and, possibly, a multiple origin of flight capabilities enhanced dispersal capabilities of paravian theropods and might thus have been crucial for their evolutionary success.

Definition. Anchiornithidae is a stem-based taxon defined as all maniraptoran theropods that are more closely related to Anchiornis huxleyi than to Passer domesticus, Archaeopteryx lithographica, Dromaeosaurus albertensis, Troodon formosus, or Oviraptor philoceratops.

Holotype. Teylers Museum TM 6928, 6929, part and counterpart of a fragmentary skeleton.

Locality and horizon. Jachenhausen locality, near Riedenburg, Bavaria, Germany. Early Tithonian laminated limestones of the Painten Formation.

Etymology. The generic name honours the late John Ostrom, who identified the Haarlem specimen as a theropod.

Conclusions

A re-evaluation of one of the twelve skeletal specimens referred to the ‘Urvogel’ Archaeopteryx, the Haarlem specimen, revealed that this specimen represents a separate taxon, Ostromia crassipes. Phylogenetic analysis identifies Ostromia as the first representative of the basal avialian clade Anchiornithidae outside eastern Asia. In combination with a biogeographic analysis, a rapid radiation of maniraptoran theropods in eastern Asia with a subsequent dispersal of many lineages in the Late Jurassic is indicated; dispersal of maniraptorans was facilitated by small body size of basal members of all clades and, possibly, several independent acquisitions of flight capabilities. In the fragmenting world of Pangean break-up during the Late Jurassic and Cretaceous, increased dispersal potential might have been a key factor to explain the success of maniraptoran, and especially avialian theropods, with dispersal events being followed by endemic radiations of different clades.

[Paleontology • 2017] Burianosaurus augustai • A Basal Ornithopod Dinosaur from the Cenomanian of the Czech Republic ---ScRaBBlE

 Burianosaurus augustai 

 Madzia, Boyd & Mazuch, 2017

 DOI:  10.1080/14772019.2017.1371258 

Abstract
During their long evolutionary history, neornithischian dinosaurs diverged into several clades with distinctive adaptations. However, the early evolution within Neornithischia and the resolution of the phylogenetic relationships of taxa situated near the base of the clade remain problematic. This is especially true for those taxa traditionally placed at the base of Ornithopoda, either as ‘hypsilophodontids’ or at the base of the diverse clade Iguanodontia. Recent studies are improving our understanding of the anatomy and relationships of these taxa, with discoveries of several new non-ankylopollexian ornithopods from South America and Europe providing key insights into early ornithopod evolution and palaeobiogeography. Here, we describe a new basal ornithopod, Burianosaurus augustai gen. et sp. nov., based on a well-preserved femur from the upper Cenomanian strata (Korycany Beds of the Peruc-Korycany Formation) of the Czech Republic. The new taxon is diagnosed by a unique suite of characters and represents the only occurrence of a Cenomanian non-avian dinosaur in Central Europe north of the Alpine Tethyan areas. Histological examination of the type specimen reveals the presence of a loosely packed Haversian system which suggests relatively mature bone from a possible young adult. Phylogenetic analyses of two different data sets, selected to test the placement of B. augustai in various parts of the neornithischian tree, reconstruct B. augustai as a basal ornithopod, firmly nested outside Ankylopollexia. These results also support a diverse Elasmaria as a basal clade within Ornithopoda and reconstruct Hypsilophodon outside Ornithopoda as the sister taxon to Cerapoda. However, the relationships of ‘hypsilophodontids’ within Neornithischia remain contentious.

Age. Late Cenomanian, early Late Cretaceous.

Derivation of name. The name Burianosaurus is derived from the surname of the Czech palaeoartist Zdenek Burian (1905–1981) who greatly influenced the perception of dinosaurs during most of the twentieth century, and saῦro & (sauros), the Greek word for ‘reptile’ or ‘lizard’.

 Burianosaurus augustai sp. nov.

Holotype. NMP Ob 203, a well-preserved, nearly complete left femur.

Derivation of name. The name augustai refers to the prominent Czech palaeontologist and prolific science populariser Josef Augusta (1903–1968).

Conclusions

Only two definitive non-avian dinosaur specimens have been described from the Czech Republic to date: NMP Ob 203, a well-preserved left femur from the upper Cenomanian (Upper Cretaceous), introduced by Fejfar et al. (2005) under temporary catalogue number IGP MZHLZ/ 2003/1, and IGS-MJ-0001 (currently DGSMU Pa 222), an isolated tetanurine tooth crown from the Oxfordian (Upper Jurassic) published by Madzia (2014).

A re-evaluation of the phylogenetic relationships of NMP Ob 203 demonstrates that this specimen actually represents a non-ankylopollexian ornithopod, here named Burianosaurus augustai gen. et sp. nov. Analysis of a modified version of the Boyd (2015) basal neornithischian data set reconstructs B. augustai as a basal member of Ornithopoda, positioned more rootward than the rhabdodontomorphs but more derived than the Gondwanan elasmarians. The new taxon can be distinguished from all other ornithopods by a unique suite of morphological characters present in the femur. From a palaeobiogeographical perspective, B. augustai represents the only occurrence of a non-avian dinosaur from the Cenomanian of Central Europe north of the Alpine Tethyan areas (Fejfar et al. 2005; Csiki-Sava et al. 2015). This discovery adds to the growing body of work demonstrating the importance of the European fossil record for studying the evolution of non-ankylopollexian ornithopods (e.g. Ősi et al. 2012; Ruiz-Omeñaca et al. 2012).

We describe the first dinosaur skeletal remains found in the Czech Republic, consisting of one complete femur and indeterminable bone fragments. They were recovered from the upper Cenomanian near-shore marine sediments deposited on the slopes of an ancient archipelago, several kilometres north of the larger Rhenish-Bohemian Island that was situated in what is now the middle of Europe. Sediments yielding dinosaur remains are of late Cenomanian age, Inoceramus pictus-I. pictus bohemicus inoceramid zone of the local lithostratigraphic unit, the Peruc-Korycany Formation. These are the first uncontested dinosaurian fossils reported from this formation and also the first Cenomanian dinosaur record in Central Europe. They document a small ornithopod belonging to an iguanodontid species comparable with similar Late Cretaceous European forms. The herbivorous dinosaur lived among a vegetation transitional between salt marsh flora, with abundant halophytic conifer Frenelopsis alata; and an alluvial plain assemblage dominated by lauroid angiosperms.

[Paleontology • 2017] Vouivria damparisensis • The Earliest Known Titanosauriform Sauropod Dinosaur from France and the Evolution of Brachiosauridae ---ScRaBBlE

Vouivria damparisensis 

Mannion​, Allain & Moine, 2017 

 DOI: 10.7717/peerj.3217 

Abstract

Brachiosauridae is a clade of titanosauriform sauropod dinosaurs that includes the well-known Late Jurassic taxa Brachiosaurus and Giraffatitan. However, there is disagreement over the brachiosaurid affinities of most other taxa, and little consensus regarding the clade’s composition or inter-relationships. An unnamed partial sauropod skeleton was collected from middle–late Oxfordian (early Late Jurassic) deposits in Damparis, in the Jura department of eastern France, in 1934. Since its brief description in 1943, this specimen has been informally known in the literature as the ‘Damparis sauropod’ and ‘French Bothriospondylus’, and has been considered a brachiosaurid by most authors. If correctly identified, this would make the specimen the earliest known titanosauriform. Coupled with its relatively complete nature and the rarity of Oxfordian sauropod remains in general, this is an important specimen for understanding the early evolution of Titanosauriformes. Full preparation and description of this specimen, known from teeth, vertebrae and most of the appendicular skeleton of a single individual, recognises it as a distinct taxon: Vouivria damparisensis gen. et sp. nov. Phylogenetic analysis of a data matrix comprising 77 taxa (including all putative brachiosaurids) scored for 416 characters recovers a fairly well resolved Brachiosauridae. Vouivria is a basal brachiosaurid, confirming its status as the stratigraphically oldest known titanosauriform. Brachiosauridae consists of a paraphyletic array of Late Jurassic forms, with Europasaurus, Vouivria and Brachiosaurus recovered as successively more nested genera that lie outside of a clade comprising (Giraffatitan + Sonorasaurus) + (Lusotitan + (Cedarosaurus + Venenosaurus)). Abydosaurus forms an unresolved polytomy with the latter five taxa. The Early Cretaceous South American sauropod Padillasaurus was previously regarded as a brachiosaurid, but is here placed within Somphospondyli. A recent study contended that a number of characters used in a previous iteration of this data matrix are ‘biologically related’, and thus should be excluded from phylogenetic analysis. We demonstrate that almost all of these characters show variation between taxa, and implementation of sensitivity analyses, in which these characters are excluded, has no effect on tree topology or resolution. We argue that where there is morphological variation, this should be captured, rather than ignored. Unambiguous brachiosaurid remains are known only from the USA, western Europe and Africa, and the clade spanned the Late Jurassic through to the late Albian/early Cenomanian, with the last known occurrences all from the USA. Regardless of whether their absence from the Cretaceous of Europe, as well as other regions entirely, reflects regional extinctions and genuine absences, or sampling artefacts, brachiosaurids appear to have become globally extinct by the earliest Late Cretaceous.

‘French Bothriospondylus’ Mannion et al., 2013

Etymology: The generic name is derived from the old French word ‘vouivre’, itself from the Latin ‘vipera’, meaning ‘viper’. In Franche-Comté, the region in which the holotype was discovered, ‘la vouivre’ (=the wyvern) is a legendary winged reptile. In the homonym novel written by the great French author Marcel Aymé, ‘La Vouivre’ is a beautiful woman who lives in the swamps in the neighbourhood of Dôle (Franche-Comté) and protects a spectacular ruby. The specific name is derived from Damparis, the type locality of the new taxon.

 Conclusions: 

A detailed redescription of a long-neglected sauropod specimen from the middle–late Oxfordian (Late Jurassic) of eastern France recognises it as a distinct brachiosaurid, Vouivria damparisensis n. gen. n. sp., that is the stratigraphically oldest known occurrence of Titanosauriformes. An expanded and revised phylogenetic analysis includes the dwarfed Late Jurassic European taxon Europasaurus within Brachiosauridae, but places the Early Cretaceous Colombian genus Padillasaurus within Somphospondyli. The past distribution of Brachiosauridae is currently restricted to Europe, North America and Africa, and the clade appears to have become globally extinct by the earliest Late Cretaceous.

[Paleontology • 2017] Soriatitan golmayensis • A New Brachiosauridae Sauropod Dinosaur from the lower Cretaceous of Europe (Soria Province, Spain) ---ScRaBBlE

Soriatitan golmayensis

 Abstract

A new dinosaur sauropod from the Golmayo Formation (upper Hauterivian-lower Barremian) in Soria province (Spain) is described as Soriatitan golmayensis gen. et sp. nov. The new material consists of one tooth, three dorsal vertebrae with ribs, a partial sacrum, five caudal centra, two caudal vertebral spines, one chevron, a humerus, an ulna, a radius, two partial ilia, two ischia, a fragment of pubis, and a partial femur. Cladistic analysis identified the material as belonging to Brachiosaruidae within Titanosauriformes. Sauropod material from the Golmayo Formation shares a diagnostic feature with Abydosaurus, Cedarosaurus, Tastavinsaurus and Venenosaurus including anteriorly deflected anterior–middle caudal neural spines and with Cedarosaurus a proximodistally straight lateral margin between the proximal head and the shaft of the humerus. Eight characters are potential autapomorphies in the sauropod from Spain, including the presence of a large rectangular ventral ridge below the preacetabular process of the ilium, the same length of the pubic and ischiadic blades in the ischium, and two lateral ridges in the lateral area of the deltopectoral crest of the humerus. The presence of Early Cretaceous brachiosarids in both, North America and Europe, give support to the hypothesis of a connection between the tectonic plates of these continents at some point during the Early Cretaceous.

Soriatitan gen. nov.
Etymology: From the Spanish province Soria where the dinosaur was found and from the Greek “titan” meaning giant in Greek mythology.

Soriatitan golmayensis sp. nov.

Etymology: In honor of the Golmayo village where the Zorralbo I site is located.

Conclusions: 

This study describes a new species of sauropod, Soriatitan golmayensis (MNS 2001/122) from the Golmayo Formation (upper Hauterivian–lower Barremian) located in Zorralbo I site in Golmayo village (Soria, Spain). This sauropod is classified as a Brachiosauridae within Titanosauriformes supported by two different phylogenetic analyses. Soriatitan shares the presence of anteriorly deflected anterior–middle caudal neural spines with Cedarosaurus, Venenosaurus and Tastavinsaurus, and a proximodistally straight lateral margin between the proximal head and the humerus shaft with Cedarosaurus. Eight characters are newly identified and are considered potential diagnostic criteria for the new possible genus and species: the caudal ribs develop a pointed anterior ridge in the middle; posterior caudal vertebra with large postzygapophyses; presence of a lateral fossa in every postzygapophysis in the posterior caudal vertebra; the presence of a rectangular ventral ridge cranial to the pubic process and below the preacetabular process in the ilium; ischiadic peduncle in the ilium three times longer in lateromedially than anteropospestiorly; the same length of the pubic peduncle and distal blade in the ischia; two lateral ridges in the lateral area of the deltopectoral crest; and the presence of the two ridges in the medial projection of the humerus head. At the moment, Soriatitan golmayensis is the first and the only brachiosarid described from the Early Cretaceous of Europe. The presence of the Early Cretaceous brachiosarid sauropods common to North America and Europe support to the presence of a possible bridge between these plates, prior to the late Hauterivian–Barremian.
