Steneosaurus Brevior
The mystery of Mystriosaurus: Redescribing the poorly known Early Jurassic teleosauroid thalattosuchians Mystriosaurus laurillardi and Steneosaurus brevior SVEN SACHS, MICHELA M. JOHNSON, MARK T. YOUNG, and PASCAL ABEL Sachs, S., Johnson, M.M., Young, M.T., and Abel, P. 2019. The mystery of Mystriosaurus: Redescribing the poorly known Early Jurassic teleosauroid thalattosuchians Mystriosaurus laurillardi and Steneosaurus brevior. Acta Palaeontologica Polonica 64 (3): 565–579. The genus Mystriosaurus, established by Kaup in 1834, was one of the first thalattosuchian genera to be named. The holotype, an incomplete skull from the lower Toarcian Posidonienschiefer Formation of Altdorf (Bavaria, southern Germany), is poorly known with a convoluted taxonomic history. For the past 60 years, Mystriosaurus has been consid- ered a subjective junior synonym of Steneosaurus. However, our reassessment of the Mystriosaurus laurillardi holotype demonstrates that it is a distinct and valid taxon. Moreover, we find the holotype of “Steneosaurus” brevior, an almost complete skull from the lower Toarcian Whitby Mudstone Formation of Whitby (Yorkshire, UK), to be a subjective ju- nior synonym of M. laurillardi. Mystriosaurus is diagnosed in having: a heavily and extensively ornamented skull; large and numerous neurovascular foramina on the premaxillae, maxillae and dentaries; anteriorly oriented external nares; and four teeth per premaxilla. Our phylogenetic analyses reveal M. laurillardi to be distantly related to Steneosaurus bollensis, supporting our contention that they are different taxa. Interestingly, our analyses hint that Mystriosaurus may be more closely related to the Chinese teleosauroid (previously known as Peipehsuchus) than any European form. Key words: Thalattosuchia, Teleosauroidea, Mystriosaurus, Jurassic, Toarcian Posidonienschiefer Formation, Whitby Mudstone Formation, Germany, UK. -

Due to the absence of diagnostic skeletal elements (the skulls are lacking), it is not possible to refer the new specimens at genus level with confidence. Although the well devel- oped dermal armour would characterise Toarcian thalattosuchians of the genera Steneosaurus (Teleosauridae) and Pelagosaurus (Metriorhynch- idae), the peculiar morphology of the osteoderms allow to tentatively refer the remains to the latter taxon (cf. Pelagosaurus sp.). The small size, along with the opening of the neurocentral vertebral sutures and, possibly, the non sutured caudal pleurapophyses, indicate that the specimens were morphologically immature at death. These “marine crocodiles” confirm the affinities between the fauna of the Calcare di Sogno Formation and coeval outcrops of central Europe that also share the presence of similar fishes and crustaceans. -

Big-Headed Marine Crocodyliforms and Why We Must Be Cautious When Using Extant Species As Body Length Proxies for Long-Extinct Relatives
Palaeontologia Electronica palaeo-electronica.org Big-headed marine crocodyliforms and why we must be cautious when using extant species as body length proxies for long-extinct relatives Mark T. Young, Márton Rabi, Mark A. Bell, Davide Foffa, Lorna Steel, Sven Sachs, and Karin Peyer ABSTRACT Body size is commonly used as a key variable for estimating ecomorphological trends at a macroevolutionary scale, making reliable body length estimates of fossil taxa critically important. Crocodylomorphs (extant crocodylians and their extinct rela- tives) evolved numerous 'aberrant' body-plans during their ~230 million-year history, ranging from ‘hooved’ terrestrial species to dolphin-like pelagic species. Such clades evolved distinct cranial and femoral scaling ratios (compared to total body length), thereby making extant taxa unsuitable proxies for estimating their body lengths. Here we illustrate that the fossil clade Teleosauridae also fits into this category. Teleosaurids were a predominately shallow marine clade that had a global distribution during the Jurassic. Known to have evolved a wide range of body lengths (2–5 m based on com- plete skeletons), there is currently no way of reliably estimating the size of incomplete specimens. This is surprising, as some teleosaurids have been considered very large (9–10 m in total length), thus making Teleosauridae the largest bodied clade during the first 100 million years of crocodylomorph evolution. Our examination and regression analyses of the best preserved teleosaurid skeletons demonstrates that: they were smaller than previously thought, with no known specimen exceeding 7.2 m in length; and that they had proportionally large skulls, and proportionally short femora, when compared to body length. -
A Speiballen from the Lower Jurassic Posidonia Shale of South Germany
N. Jb. Geol. Paläont. Abh. 267/1, 117–124 Article Published online December 2012 A Speiballen from the Lower Jurassic Posidonia Shale of South Germany Detlev Thies and Rolf Bernhard Hauff with 1 figure Thies, D. & hauff, R.B. (2013): A Speiballen from the Lower Jurassic Posidonia Shale of South Ger- many. – N. Jb. Geol. Paläont. Abh., 267: 117–124; Stuttgart. Abstract: A Speiballen (regurgitated compacted mass of indigestible stomach contents) from the Lower Jurassic Posidonia Shale of Ohmden, South Germany contains remains of four specimens of the actinopterygian Dapedium sp., the specific identity of which remains obscure, and a lower jaw of a specimen identified as Lepidotes sp. A list of five suitable characters is proposed to distinguish fossil Speiballen containing specimens from other vertebrate fossils. Large, potentially piscivorous animals in the Posidonia Shale ecosystem comprise chondrichthyans (Hybodus), other actinoptery- gians (pachycormiforms) and marine reptiles (crocodilians, ichthyosaurs, plesiosaurs). Only juvenile ichthyosaurs (Stenopterygius) are known to have preyed on Dapedium. Available data are, however, insufficient to clearly identify the Speiballen producer. The heavy scale armour of basal neoptery- gians such as Dapedium undoubtedly hampered digestion of these fishes and in this way provided additional protection against predators. Key words: Jurassic, Fossillagerstätte, Holzmaden, ecosytem, predation. 1.

Young*1, Sven Sachs2 & Pascal Abel3 Introduction: To most people, crocodilians are large-bodied carnivores that have been unchanged since the age of the dinosaurs. However, during their 230 million-year history, modern crocodilians and their extinct relatives evolved a stunning diversity of body plans, with many looking very different from those alive today (crocodiles, alligators, caimans and gharials). -
