To overcome this difficulty in assessing the maturity of extinct archosaurian reptiles—crocodylians, birds and their extinct relatives—many studies employ bone histology to observe indicators of the developmental stage reached by a given individual. However, the relationship between gross morphological and histological indicators of maturity has not been examined in most archosaurian groups. In this study, we examined the gross morphology of a hypothesized growth series of Dromomeron romeri femora (96.6–144.4 mm long), the first series of a non- dinosauriform dinosauromorph available for such a study. We also histologically sampled several individuals in this growth series. Previous studies reported that Submitted 7 August 2018 D. romeri lacks well-developed rugose muscle scars that appear during ontogeny in Accepted 20 December 2018 closely related dinosauromorph taxa, so integrating gross morphology and Published 11 February 2019 histological signal is needed to determine reliable maturity indicators for early Corresponding author Christopher T. -

Press Release
Press Release For Immediate Release January 2, 2012 Media Contact Cynthia Ehlinger Marketing Associate 203 413-6756 | [email protected] Take a Walk Through the Dinosaur Age. Chinasaurs: Dinosaur Discoveries from China Opens January 26, 2013 at Bruce Museum Szechuanosaurus Szechuan Province, China Late Jurassic Period, 160 to 144 million years ago Since the first paleontological expedition to Mongolia by Roy Chapman Andrews of the American Museum of Natural History in the 1920s, the allure of discovering exotic Asian dinosaurs has been the dream of every paleontologist. Subsequently, dinosaurs from China have been unearthed revealing their relationships to birds as evidenced by the presence of feathers together with scales. Several of the most spectacular of these dinosaurs are coming to the Bruce Museum in Greenwich, Connecticut, beginning January 26 and continuing through April 21, 2013. Chinasaurs: Dinosaur Discoveries from China welcomes visitors to walk among the skeletons, skulls, nests and eggs of more than a dozen of these rare Asian dinosaurs. From the huge 32-foot long, meat- eating Yangchuanosaurus to the gazelle-sized plant eaters such as Psittacosaurus, the prehistoric fossils of the Far East provide an exciting experience for dinosaur enthusiasts. Skeletons of all sizes from the Triassic, Jurassic and Cretaceous periods tell the tale of dinosaur diversification and shifting continents. Maps, video and activity tables help visitors of all ages learn more about the specimens on view. One display features a Jurassic battle between the plated, plant-eating Tuojiangosaurus with a spiked tail and the large meat-eating Monolophosaurus with teeth like steak Page 1 of 3 Press Release knives. -
A New Troodontid Theropod Dinosaur from the Lower Cretaceous of Utah
A New Troodontid Theropod Dinosaur from the Lower Cretaceous of Utah Phil Senter1*, James I. Kirkland2, John Bird3, Jeff A. Bartlett4 1 Department of Biological Sciences, Fayetteville State University, Fayetteville, North Carolina, United States of America, 2 Utah Geological Survey, Salt Lake City, Utah, United States of America, 3 College of Eastern Utah Prehistoric Museum, Price, Utah, United States of America, 4 College of Eastern Utah, Price, Utah, United States of America Abstract Background: The theropod dinosaur family Troodontidae is known from the Upper Jurassic, Lower Cretaceous, and Upper Cretaceous of Asia and from the Upper Jurassic and Upper Cretaceous of North America. Before now no undisputed troodontids from North America have been reported from the Early Cretaceous. Methodology/Principal Findings: Herein we describe a theropod maxilla from the Lower Cretaceous Cedar Mountain Formation of Utah and perform a phylogenetic analysis to determine its phylogenetic position. The specimen is distinctive enough to assign to a new genus and species, Geminiraptor suarezarum. Phylogenetic analysis places G. suarezarum within Troodontidae in an unresolved polytomy with Mei, Byronosaurus, Sinornithoides, Sinusonasus,andTroodon + (Saurornithoides + Zanabazar). Geminiraptor suarezarum uniquely exhibits extreme pneumatic inflation of the maxilla internal to the antorbital fossa such that the anterior maxilla has a triangular cross-section. Unlike troodontids more closely related to Troodon, G. suarezarum exhibits bony septa between the dental alveoli and a promaxillary foramen that is visible in lateral view. Conclusions/Significance: This is the first report of a North American troodontid from the Lower Cretaceous. It therefore contributes to a fuller understanding of troodontid biogeography through time. It also adds to the known dinosaurian fauna of the Cedar Mountain Formation. -

Dinosaurs Put All Colored Birds' Eggs in One Basket, Evolutionarily Speaking 31 October 2018
Dinosaurs put all colored birds' eggs in one basket, evolutionarily speaking 31 October 2018 red and blue, to create all of the various egg colors, spots, and speckles. Wiemann and her colleagues analyzed 18 fossil dinosaur eggshell samples from around the world, using non-destructive laser microspectroscopy to test for the presence of the two eggshell pigments. They found them in eggshells belonging to Eumaniraptoran dinosaurs, which include small, carnivorous dinosaurs such as Velociraptor. Fossil theropod dinosaur egg (front), with corvid eggs in a nest. Fossil Deinonychus and oviraptor eggs were probably similar in coloration to corvid eggs.

Only two such giant “raptors” have been described from North America. Here, we describe a new giant dromaeosaurid, Dakotaraptor steini gen. et sp. nov., from the Hell Creek Formation of South Dakota. The discovery represents the first giant dromaeosaur from the Hell Creek Formation, and the most recent in the fossil record worldwide. A row of prominent ulnar papilli or “quill knobs” on the ulna is our first clear evidence for feather quills on a large dromaeosaurid forearm and impacts evolutionary reconstructions and functional morphology of such derived, typically flight-related features. -

This paper reviews published studies and provides new data on archosaur lineage origination, diversity and lineage evolution, morpho- logical disparity, rates of morphological character change, and faunal abundance during the Triassic–Early Jurassic. The fundamental archosaur lineages originated early in the Triassic, in concert with the highest rates of character change. Disparity and diversity peaked later, during the Norian, but the most significant increase in disparity occurred before maximum diversity. Archo- saurs were rare components of Early–Middle Triassic faunas, but were more abundant in the Late Triassic and pre-eminent globally by the Early Jurassic. The archosaur radiation was a drawn-out event and major components such as diversity and abundance were discordant from each other. -
