The phylogenetic affinities of the bizarre Late Cretaceous Romanian theropod Balaur bondoc (Dinosauria, Maniraptora): dromaeosaurid or flightless bird? [PDF]

PeerJ, 2015
The exceptionally well-preserved Romanian dinosaur Balaur bondoc is the most complete theropod known to date from the Upper Cretaceous of Europe. Previous studies of this remarkable taxon have included its phylogenetic interpretation as an aberrant ...

First find of the dromaeosauridae (dinosauria: dromaeosauridae) ungual from the late cretaceous Blagoveschensk dinosaur locality (Amur Region, Russia)

Доклады Академии наук, 2019
Dromaeosaurid ungual from the Blagoveschensk locality studied for the first time. Dromaeosaurid presence amongst other taxa points on high biodiversity in Amur region, on the eve of K-T event.

Morphological disparity in theropod jaws: comparing discrete characters and geometric morphometrics

Palaeontology, Volume 63, Issue 2, Page 283-299, March 2020., 2020
Abstract Disparity, the diversity of form and function of organisms, can be assessed from cladistic or phenetic characters, and from discrete characters or continuous characters such as landmarks, outlines, or ratios. But do these different methods of assessing disparity provide comparable results?

Paravian Phylogeny and the Dinosaur-Bird Transition: An Overview

Frontiers in Earth Science, 2019
Recent years witnessed the discovery of a great diversity of early birds as well as closely related non-avian theropods, which modified previous conceptions about the origin of birds and their flight. We here present a review of the taxonomic composition
