Independent Evidence for the Preservation of Endogenous Bone Biochemistry in a Specimen of Tyrannosaurus rex

BIOLOGY-BASEL, 12(2).

By: J. Anne*, A. Canoville*, N. Edwards*, M. Schweitzer n & L. Zanno n

author keywords: synchrotron; bone remodeling; elemental analysis; molecular paleontology; diagenetic alteration
TL;DR: It is shown that trace elements incorporated by the living animal during bone deposition and remodeling, such as zinc, are preserved in the fossil bone in a pattern similar to what is seen in modern bird bones, which further support the preservation of original biological material in this T. rex.

Chronic fracture and osteomyelitis in a large-bodied ornithomimosaur with implications for the identification of unusual endosteal bone in the fossil record

Chinzorig, T., Beguesse, K. A., Canoville, A., Phillips, G., & Zanno, L. E. (2022, October 4). ANATOMICAL RECORD-ADVANCES IN INTEGRATIVE ANATOMY AND EVOLUTIONARY BIOLOGY, Vol. 10.

author keywords: dinosaur; fracture; infection; medullary bone; theropod
MeSH headings : Animals; Fossils; Bone and Bones; Fractures, Bone / diagnostic imaging; X-Ray Microtomography; Osteomyelitis / diagnostic imaging
TL;DR: The external gross morphology and internal architecture of a pathologic right second metatarsal of a large‐bodied ornithomimid from the Santonian (Upper Cretaceous) Eutaw Formation in Mississippi is described, interpreted as evidence of blunt force trauma to the foot that could have resulted from intra‐ or interspecific competition or predator–prey interaction.

MeSH headings : Animals; Fused Teeth; Tooth / anatomy & histology; Vertebrates; Sharks / anatomy & histology; Fishes; Mammals
TL;DR: It is argued that the definitions and diagnostic criteria for dental pathologies in vertebrates require standardization in order to advance macroevolutionary studies of feeding trauma in deep time and to link developmental, paleobiological, and/or paleoenvironmental factors to gemination/fusion in polyphyodont taxa.

Ed(s): L. Claessens

MeSH headings : Animals; Fossils; Ecosystem; Dinosaurs / anatomy & histology; North America; Grasshoppers; Appalachian Region
TL;DR: An assemblage of ornithomimosaurian materials from the Santonian Eutaw Formation of Mississippi provide key information on the diversity and distribution of North American ornithmimosaurs and Appalachian dinosaurs and fit with broader evidence of multiple cohabiting species of ornithsomimosaurs in Late Cretaceous ecosystems of Laurasia.

Palaeopathological evidence for intraspecific combat in ankylosaurid dinosaurs

BIOLOGY LETTERS, 18(12).

By: V. Arbour*, L. Zanno n & D. Evans*

author keywords: Dinosauria; Ankylosauria; sexual selection; animal weaponry
MeSH headings : Animals; Dinosaurs; Mammals
TL;DR: It is suggested that sexual selection drove the evolution of this impressive weapon and changes the prevailing view of ankylosaurs, suggesting they were behaviorally complex animals that likely engaged in ritualized combat for social dominance as in other ornithischian dinosaurs and mammals.

MeSH headings : Animals; Biological Evolution; Bone and Bones / anatomy & histology; Bone and Bones / metabolism; Dinosaurs / anatomy & histology; Dinosaurs / metabolism; Fossils; Keratan Sulfate / metabolism
TL;DR: The results suggest that the presence of keratan sulfate is not exclusive evidence for MB, but rather must be used as one in a suite of criteria available for identifying medullary bone (and thus gravid females) in non‐avian dinosaur specimens. (via Semantic Scholar)

Growing up Tyrannosaurus rex : Osteohistology refutes the pygmy “ Nanotyrannus ” and supports ontogenetic niche partitioning in juvenile Tyrannosaurus

Science Advances, 6(1).

MeSH headings : Animals; Body Size; Bone and Bones / ultrastructure; Dinosaurs / anatomy & histology; Femur / ultrastructure; Fossils / ultrastructure; Tibia / ultrastructure; Tooth / ultrastructure
TL;DR: Together, the results support the synonomization of “Nanotyrannus” into Tyrannosaurus and fail to support the hypothesized presence of a sympatric tyrannosaurid species of markedly smaller adult body size, but suggest that this species singularly exploited mid- to large-sized theropod niches at the end of the Cretaceous.

Quantifying shape and ecology in avian pedal claws: the relationship between the bony core and keratinous sheath

author keywords: claw; individual variation; morphometrics; phylogenetic comparative methods
TL;DR: The bony claw core and keratinous sheath are significantly correlated, and the degree of functional integration does not differ across ecological groups; however, some separation between ecological groups is evident and a gradual shift from the claw shape of ground‐dwelling birds to those of predatory birds is evident.

Systemic distribution of medullary bone in the avian skeleton: ground truthing criteria for the identification of reproductive tissues in extinct Avemetatarsalia

MeSH headings : Animals; Birds / classification; Bone and Bones / anatomy & histology; Extinction, Biological; Female; Fossils; Phylogeny; Reproduction / physiology; Species Specificity; Tomography, X-Ray Computed
TL;DR: Although its skeletal distribution varies interspecifically, MB is found to be a systemic tissue that can be deposited within virtually all skeletal regions, including cranial elements, and evidence that the deposition of MB is dictated by skeletal distribution patterns of both pneumaticity and bone marrow; two factors linked to ecology (body size, foraging).

By: K. Button n, H. You*, J. Kirkland* & L. Zanno n

author keywords: Dinosaur teeth; Therizinosauria; Von ebner; Dentin; Enamel microstructure; Histology; Tooth growth
TL;DR: A significant reduction in the rate of enamel apposition is recorded contrasted with increased relative enamel thickness between early and later diverging therizinosaurians that coincides with anatomical evidence for increased specializations to herbivory in the clade. (via Semantic Scholar)

Bony cranial ornamentation linked to rapid evolution of gigantic theropod dinosaurs

Nature Communications, 7(1).

By: T. Gates n, C. Organ* & L. Zanno n

TL;DR: It is found that body size evolved directionally toward phyletic giantism an order of magnitude faster in theropod species possessing ornaments compared with unadorned lineages, and there is novel, quantitative support for a shift in selective pressures on socio-sexual display mechanisms in the theropods coincident with the evolution of pennaceous feathers.
