Rocky Start of Dinosaur National Monument (USA), the World's First Dinosaur Geoconservation Site
Original Article Rocky Start of Dinosaur National Monument (USA), the World's First Dinosaur Geoconservation Site Kenneth Carpenter Prehistoric Museum, Utah State University Eastern Price, Utah 80504 USA Abstract The quarry museum at Dinosaur National Monument, which straddles the border between the American states of Colorado and Utah, is the classic geoconservation site where visitors can see real dinosaur bones embedded in rock and protected from the weather by a concrete and glass structure. The site was found by the Carnegie Museum in August 1909 and became a geotourist site within days of its discovery. Within a decade, visitors from as far as New Zealand traveled the rough, deeply rutted dirt roads to see dinosaur bones in the ground for themselves. Fearing that the site would be taken over by others, the Carnegie Museum attempted twice to take the legal possession of the land. The second attempt had consequences far beyond what the Museum intended when the federal government declared the site as Dinosaur National Monument in 1915, thus taking ultimate control from the Carnegie Museum. Historical records and other archival data (correspondence, diaries, reports, newspapers, hand drawn maps, etc.) are used to show that the unfolding of events was anything but smooth. It was marked by misunderstanding, conflicting Corresponding Author: goals, impatience, covetousness, miscommunication, unrealistic expectation, intrigue, and some Kenneth Carpenter paranoia, which came together in unexpected ways for both the Carnegie Museum and the federal Utah State University Eastern Price, government.

As initially designated in 2016, BENM encompassed 1.3 million acres of land with exceptionally fossiliferous rock units. Subsequently, in December 2017, presidential action reduced BENM to two smaller management units (Indian Creek and Shash Jáá). Although the paleontological resources of BENM are extensive and abundant, they have historically been under-studied. Here, we summarize prior paleontological work within the original BENM boundaries in order to provide a complete picture of the paleontological resources, and synthesize the data which were used to support paleontological resource protection. -
Possible Evidence of Gregarious Behavior in Tyrannosaurids
GAIA N'15, LlSBOAlLISBON, DEZEMBRO/DECEMBER 1998, pp. 271-277 (ISSN: 0871-5424) POSSIBLE EVIDENCE OF GREGARIOUS BEHAVIOR IN TYRANNOSAURIDS Philip J. CURRIE Royal Tyrrell Museum of Palaeontology. Box 7500 Drumheller, ALBERTA TOJ OYO. CANADA ABSTRACT: In 1910, a collecting party from the American Museum of Natural History led by Barnum Brown floated down the Red Deer Riverof Alberta. In the Horseshoe Canyon Forma tion (Edmonton Group, Campanian-Maastrichtian, Upper Cretaceous) close to the mouth of Big Valley Creek, they excavated semi-articulated skeletons of several individuals of Alber tosaurus sarcophagus OSBORN, 1905 from a single quarry. Other than the tyrannosaurids, only two hadrosaur phalanges were recovered. Eight articulated feet with associated limb bones were given catalogue numbers, as was an articulated string oftwenty-five caudal ver tebrae_ The remaining tyrannosaurid fossils that could not be associated with any of these specimens or with each other were all assigned a single number. Brown's other discoveries of well-preserved dinosaur skeletons in southern Alberta overshadowed the tyrannosaurid find, and the specimens were largely forgotten. However, it is the best evidence that exists to suggest that tyrannosaurids may have been gregarious animals. The almost complete lack of herbivore bones from the excavation suggests that this was probably not a predator trap, such as has been postulated for the Allosaurus MARSH, 1877 accumulation at the Cleveland-Lloyd Quarry near Price, Utah. Comparative measurements indicate that juvenile tyrannosaurids were probably almost as fast at running as ornithomimids. This suggests a division of labor amongst a hunting pack of tyrannosaurids.

The Behavioral Implications of a Multi-Individual Bonebed of a Small Theropod Dinosaur

Among vertebrate fossils from the Upper Cretaceous Bajo Barreal Formation of Patagonia, five individuals of the small, non-avian theropod dinosaur Aniksosaurus darwini were recovered. Group behavior is an important aspect of dinosaur paleoecology, but it is not well- documented and is poorly understood among non-avian Theropoda. Methods/Principal Findings: The taphonomic association of individuals from the Bajo Barreal Formation and aspects of their bone histology suggest gregarious behavior for Aniksosaurus, during at least a portion of the life history of this species. Histology indicates that the specimens were juvenile to sub-adult individuals. In addition, morphological differences between individuals, particularly proportions of the appendicular bones, are probably -

Dipnoan from the Upper Triassic of East Greenland and Remarks About Palaeobiogeography of Ptychoceratodus
Dipnoan from the Upper Triassic of East Greenland and remarks about palaeobiogeography of Ptychoceratodus WOJCIECH PAWLAK, MATEUSZ TAŁANDA, TOMASZ SULEJ, and GRZEGORZ NIEDŹWIEDZKI Pawlak, W., Tałanda, M., Sulej, T., and Niedźwiedzki, G. 2020. Dipnoan from the Upper Triassic of East Greenland and remarks about palaeobiogeography of Ptychoceratodus. Acta Palaeontologica Polonica 65 (3): 561–574. Here we present a description of the dipnoan remains collected from the middle to upper Norian (Upper Triassic) of Jameson Land, East Greenland. The specimens consist of isolated tooth plates and skull bones of Ptychoceratodus, the most complete Late Triassic dipnoan material from Greenland. This genus is reported for the first time from the Upper Triassic of Greenland. The studied material belongs to Ptychoceratodus rectangulus previously known from the middle–upper Norian of Germany. It fills the biogeographical gap between the records of the Germanic and the Jameson Land basins. A reconstruction of the skull roof is provided, based on isolated bones collected from the same bone-bed. Their good preservation enables recognition of the sensory line pits, arranged similarly as in the extant Protopterus, suggesting a comparable mode of life. This finding has implications for our understanding of the dis- parity in Ptychoceratodus dipnoans, as well as the morphology between closely related dipnoans of the Late Triassic ecosystems. Key words: Dipnoi, Ptychoceratodus, Triassic, Norian, Greenland, Carlsberg Fjord Beds.
