Royal Society Open Science, 2021 Carcharodontosauria is a group of medium to large-sized predatory theropods, distributed worldwide during the Cretaceous. These theropods were probably the apex predators of Asiamerica in the early Late Cretaceous prior to the ascent of tyrannosaurids ...

On Dinosaur Reconstruction: Posture of Dinosaurs
Open Journal of Geology, 2021 Dinosaurs due to their diverse species and peculiar forms have drawn the interest of both artists and scientists. One way to unlock the unknown life of dinosaurs is to reconstruct dinosaurs through drawings, computer animations or sculptures. Following the Introduction on “Dinosaur Reconstruction” by the present authors, where important Paleontological

The extinction of the dinosaurs [PDF]
Biological Reviews, 2014 ABSTRACTNon‐avian dinosaurs went extinct 66 million years ago, geologically coincident with the impact of a large bolide (comet or asteroid) during an interval of massive volcanic eruptions and changes in temperature and sea level. There has long been fervent debate about how these events affected dinosaurs.

Royal Society Open Science, 2021 During the Cretaceous, diversifications and turnovers affected terrestrial vertebrates experiencing the effects of global geographical change. However, the poor fossil record from the early Late Cretaceous has concealed how dinosaurs and other ...

New records of theropods from the latest Cretaceous of New Jersey and the Maastrichtian Appalachian fauna [PDF]
Royal Society Open Science, 2019 The faunal changes that occurred in the few million years before the Cretaceous–Palaeogene extinction are of much interest to vertebrate palaeontologists. Western North America preserves arguably the best fossil record from this time, whereas terrestrial

Royal Society Open Science, 2023 Trackways provide essential data on the biogeographic distribution, locomotion and behaviour of dinosaurs. Cretaceous dinosaur trackways are abundant in the Americas, Europe, North Africa and East Asia, but are less well documented in Central Asia ...

Neurovascular anatomy of dwarf dinosaur implies precociality in sauropods
eLife, 2022 Macronaria, a group of mostly colossal sauropod dinosaurs, comprised the largest terrestrial vertebrates of Earth’s history. However, some of the smallest sauropods belong to this group as well.

Spinosaurus is not an aquatic dinosaur
eLife, 2022 A predominantly fish-eating diet was envisioned for the sail-backed theropod dinosaur Spinosaurus aegyptiacus when its elongate jaws with subconical teeth were unearthed a century ago in Egypt.

Dinosaur diversification rates were not in decline prior to the K-Pg boundary [PDF]
Royal Society Open Science, 2020 Determining the tempo and mode of non-avian dinosaur extinction is one of the most contentious issues in palaeobiology. Extensive disagreements remain over whether their extinction was catastrophic and geologically instantaneous or the culmination of ...
