The Late Triassic Thecodontosaurus antiquus occupies a basal position within Sauropodomorpha, being a key taxon for documenting how those morphofunctional transitions occurred. Here, we redescribe the braincase osteology and reconstruct the neuroanatomy of Thecodontosaurus, based on computed tomography data. The braincase of Thecodontosaurus shares the presence of medial basioccipital components of the basal tubera and a U-shaped basioccipital–parabasisphenoid suture with other basal sauropodomorphs and shows a distinct combination of characters: a straight outline of the braincase floor, an undivided metotic foramen, an unossified gap, large floccular fossae, basipterygoid processes perpendicular to the cultriform process in lateral view and a rhomboid foramen magnum. We reinterpret these braincase features in the light of new discoveries in dinosaur anatomy. Our endocranial reconstruction reveals important aspects of the palaeobiology of Thecodontosaurus, supporting a bipedal stance and cursorial habits, with adaptations to retain a steady head and gaze while moving. -

Basal titanosauriforms were present in Japan during the Early Cretaceous before Aptian, and there is the possibility that the Brachiosauridae may have been included. Basal titanosauriforms with peg-like teeth were present during the “mid” Cretaceous, while the Titanosauria with peg-like teeth was present during the middle of Late Cretaceous. Recent excavations of Cretaceous sauropods in Asia showed that multiple lineages of sauropods lived throughout the Cretaceous in Asia. Japanese fossil records of sauropods are conformable with this hypothesis. Key words: Sauropod, Titanosauriforms, tooth, Cretaceous, Japan.

Today is truly a cause for celebration, as our students present the results of the great work they’ve been engaged in during the past year. Students representing all four class years and from across the disciplines are demonstrating today what’s best about the Gettysburg College experience— intentional collaborations between students and their mentors such that students acquire both knowledge and skills that can be applied to many facets of their future personal and professional lives. The benefits for those who mentor these young adults may, at first, be more difficult to discern. Most of those who engage in mentoring do it because they enjoy being around students who are eager to learn what they have to teach them. -

Re-Description of the Sauropod Dinosaur Amanzia (“Ornithopsis
Schwarz et al. Swiss J Geosci (2020) 113:2 https://doi.org/10.1186/s00015-020-00355-5 Swiss Journal of Geosciences ORIGINAL PAPER Open Access Re-description of the sauropod dinosaur Amanzia (“Ornithopsis/Cetiosauriscus”) greppini n. gen. and other vertebrate remains from the Kimmeridgian (Late Jurassic) Reuchenette Formation of Moutier, Switzerland Daniela Schwarz1* , Philip D. Mannion2 , Oliver Wings3 and Christian A. Meyer4 Abstract Dinosaur remains were discovered in the 1860’s in the Kimmeridgian (Late Jurassic) Reuchenette Formation of Moutier, northwestern Switzerland. In the 1920’s, these were identifed as a new species of sauropod, Ornithopsis greppini, before being reclassifed as a species of Cetiosauriscus (C. greppini), otherwise known from the type species (C. stewarti) from the late Middle Jurassic (Callovian) of the UK. The syntype of “C. greppini” consists of skeletal elements from all body regions, and at least four individuals of diferent sizes can be distinguished. Here we fully re-describe this material, and re-evaluate its taxonomy and systematic placement. The Moutier locality also yielded a theropod tooth, and fragmen- tary cranial and vertebral remains of a crocodylomorph, also re-described here. “C.” greppini is a small-sized (not more than 10 m long) non-neosauropod eusauropod. Cetiosauriscus stewarti and “C.” greppini difer from each other in: (1) size; (2) the neural spine morphology and diapophyseal laminae of the anterior caudal vertebrae; (3) the length-to-height proportion in the middle caudal vertebrae; (4) the presence or absence of ridges and crests on the middle caudal cen- tra; and (5) the shape and proportions of the coracoid, humerus, and femur. -

After two years of uncertainty, the council-owned cattle selling facility was saved from permanent closure after elected members backed a motion to keep the gates open conditional on the yards maintaining a yearly throughput of 8500. At Tuesday night’s council meeting, elected members resumed discussion on a motion by cattle producer and Councillor Moira Neagle to continue the operations of the facility until 2025, de- velop a management plan for the faculty and consider recurrent funding for capi- tal upgrades. But Penola-based Rick Paltridge - who has been a vocal opponent of continuing the saleyards - told the chamber he had spoken to “numerous people around the region” including stock agents, truck drivers, meat buyers and farmers who he claimed believed the saleyards should be closed down.

A New Middle Jurassic Diplodocoid Suggests an Earlier Dispersal and Diversification of Sauropod Dinosaurs
ARTICLE DOI: 10.1038/s41467-018-05128-1 OPEN A new Middle Jurassic diplodocoid suggests an earlier dispersal and diversification of sauropod dinosaurs Xing Xu1, Paul Upchurch2, Philip D. Mannion 3, Paul M. Barrett 4, Omar R. Regalado-Fernandez 2, Jinyou Mo5, Jinfu Ma6 & Hongan Liu7 1234567890():,; The fragmentation of the supercontinent Pangaea has been suggested to have had a profound impact on Mesozoic terrestrial vertebrate distributions. One current paradigm is that geo- graphic isolation produced an endemic biota in East Asia during the Jurassic, while simul- taneously preventing diplodocoid sauropod dinosaurs and several other tetrapod groups from reaching this region. Here we report the discovery of the earliest diplodocoid, and the first from East Asia, to our knowledge, based on fossil material comprising multiple individuals and most parts of the skeleton of an early Middle Jurassic dicraeosaurid. The new discovery challenges conventional biogeographical ideas, and suggests that dispersal into East Asia occurred much earlier than expected. Moreover, the age of this new taxon indicates that many advanced sauropod lineages originated at least 15 million years earlier than previously realised, achieving a global distribution while Pangaea was still a coherent landmass. 1 Key Laboratory of Evolutionary Systematics of Vertebrates, Institute of Vertebrate Paleontology & Paleoanthropology, Chinese Academy of Sciences, 100044 Beijing, China. 2 Department of Earth Sciences, University College London, Gower Street, London WC1E 6BT, UK. 3 Department of Earth Science and Engineering, Imperial College London, South Kensington Campus, London SW7 2AZ, UK. 4 Department of Earth Sciences, Natural History Museum, Cromwell Road, London SW7 5BD, UK. 5 Natural History Museum of Guangxi, 530012 Nanning, Guangxi, China. -

Body-Size Evolution in the Dinosauria
8 Body-Size Evolution in the Dinosauria Matthew T. Carrano Introduction The evolution of body size and its influence on organismal biology have received scientific attention since the earliest decades of evolutionary study (e.g., Cope, 1887, 1896; Thompson, 1917). Both paleontologists and neontologists have attempted to determine correlations between body size and numerous aspects of life history, with the ultimate goal of docu- menting both the predictive and causal connections involved (LaBarbera, 1986, 1989). These studies have generated an appreciation for the thor- oughgoing interrelationships between body size and nearly every sig- nificant facet of organismal biology, including metabolism (Lindstedt & Calder, 1981; Schmidt-Nielsen, 1984; McNab, 1989), population ecology (Damuth, 1981; Juanes, 1986; Gittleman & Purvis, 1998), locomotion (Mc- Mahon, 1975; Biewener, 1989; Alexander, 1996), and reproduction (Alex- ander, 1996). An enduring focus of these studies has been Cope’s Rule, the notion that body size tends to increase over time within lineages (Kurtén, 1953; Stanley, 1973; Polly, 1998). Such an observation has been made regarding many different clades but has been examined specifically in only a few (MacFadden, 1986; Arnold et al., 1995; Jablonski, 1996, 1997; Trammer & Kaim, 1997, 1999; Alroy, 1998). The discordant results of such analyses have underscored two points: (1) Cope’s Rule does not apply universally to all groups; and (2) even when present, size increases in different clades may reflect very different underlying processes. Thus, the question, “does Cope’s Rule exist?” is better parsed into two questions: “to which groups does Cope’s Rule apply?” and “what process is responsible for it in each?” Several recent works (McShea, 1994, 2000; Jablonski, 1997; Alroy, 1998, 2000a, 2000b) have begun to address these more specific questions, attempting to quantify patterns of body-size evolution in a phylogenetic (rather than strictly temporal) context, as well as developing methods for interpreting the resultant patterns. -
