BMC Ecology and EvolutionBackground Microraptor is known as the most significant example of extended feathering on the legs of a paravian, both fossil and modern. Its striking difference with most paravians contributes to the multiple theories on the function of its conspicuous ...

Journal of Vertebrate Paleontology, 2017 Buitreraptor gonzalezorum is a paravian theropod from the Late Cretaceous of Patagonia that has been recovered as an unenlagiine dromaeosaurid in several phylogenies. It was preliminarily described in a brief article, but a detailed osteology has not been published to date.

Journal of Anatomy, Volume 242, Issue 6, Page 1124-1145, June 2023., 2023 Spinosaurids were unusual large‐bodied tetanuran theropods with semi‐aquatic ecologies. The neuroanatomy of baryonychine spinosaurids has yet to be studied, and may inform about the early evolution of the spinosaurid brain and sensory capabilities. With unexceptional hearing and olfaction, baryonychine endocasts share morphological similarities with ...

Papers in Palaeontology, Volume 9, Issue 2, March/April 2023., 2023 Abstract Current research suggests that the initial radiation of maniraptoran theropods occurred in the Middle Jurassic, although their fossil record is known almost exclusively from the Cretaceous. However, fossils of Jurassic maniraptorans are scarce, usually consisting solely of isolated teeth, and their identifications are often disputed.

A microraptorine (Dinosauria–Dromaeosauridae) from the Late Cretaceous of North America [PDF]
Proceedings of the National Academy of Sciences, 2009 The fossil assemblages of the Late Cretaceous of North America are dominated by large-bodied dinosaur species. Associated skeletons of small dinosaurs are exceedingly rare, and small (<10 kg) carnivorous theropods have not previously been reported from these beds.

Palaeontology, Volume 65, Issue 3, May/June 2022., 2022 Abstract Bite traces on fossil bones are key to deciphering feeding ecology and trophic interactions of vertebrate past ecosystems. However, similarities between traces produced by different carnivorous taxa with similar dentitions, and misidentifications due to equifinality, hinder confident identifications of the bite makers.
