The Anatomical Record, Volume 306, Issue 7, Page 1864-1879, July 2023., 2023 Abstract Paleopathological diagnoses provide key information on the macroevolutionary origin of disease as well as behavioral and physiological inferences that are inaccessible via direct observation of extinct organisms. Here we describe the external gross morphology and internal architecture of a pathologic right second metatarsal (MMNS VP‐6332) of a

A new primitive Neornithischian dinosaur from the Jurassic of Patagonia with gut contents. [PDF]
Sci Rep, 2017 We describe a new species of an ornithischian dinosaur, Isaberrysaura mollensis gen. et sp. nov. The specimen, consisting in an almost complete skull and incomplete postcranium was collected from the marine-deltaic deposits of the Los Molles Formation ...

Palaeontology, Volume 66, Issue 4, July/August 2023., 2023 Abstract Various terrestrial tetrapods convergently evolved to gigantism (large body sizes and masses), the most extreme case being sauropod dinosaurs. Heavy weight‐bearing taxa often show external morphological features related to this condition, but also adequacy in their limb bone inner structure: a spongiosa filling the medullary area and a rather ...

Review of European, Comparative &International Environmental Law, Volume 31, Issue 2, Page 182-198, July 2022., 2022 Abstract Restoring functional ecosystems in Europe inter alia requires restoring large mammal (megafauna) diversity and densities to levels well above the current downgraded state, which results from a human‐driven wave of megafauna extinctions and extirpations in the Late Pleistocene and Holocene.

Palaeontology, Volume 65, Issue 3, May/June 2022., 2022 Abstract Little is known about the large‐scale evolutionary patterns of skull size relative to body size, and the possible drivers behind these patterns, in Archosauromorpha. For example, the large skulls of erythrosuchids, a group of non‐archosaurian archosauromorphs from the Early and Middle Triassic, and of theropod dinosaurs are regarded as ...

The extinct, giant giraffid Sivatherium giganteum: skeletal reconstruction and body mass estimation [PDF]
, 2016 Sivatherium giganteum is an extinct giraffid from the Plio–Pleistocene boundary of the Himalayan foothills. To date, there has been no rigorous skeletal reconstruction of this unusual mammal.

A survey of dinosaur diversity by clade, age, place of discovery and year of description [PDF]
, 2014 Dinosaur diversity is analyzed in terms of the number of valid genera within each major clade, Mesozoic age, place of discovery and year of description. Aves (Archaeopteryx + Neornithes) is excluded. Nomina nuda and nomina dubia are not counted.

Downsizing a giant: Re-evaluating Dreadnoughtus body mass [PDF]
, 2015 Estimates of body mass often represent the founding assumption on which biomechanical and macroevolutionary hypotheses are based. Recently, a scaling equation was applied to a newly discovered titanosaurian sauropod dinosaur (Dreadnoughtus), yielding a ...
