Upper Cretaceous European theropod palaeobiodiversity, palaeobiogeography and the intra‐Maastrichtian faunal turnover: new contributions from the Iberian fossil site of Laño

open access: yesPapers in Palaeontology, Volume 8, Issue 1, January/February 2022., 2022
Abstract A total of 227 theropod teeth have so far been recovered from the upper Campanian Laño site (northern Iberian Peninsula). The teeth were studied for their qualitative and quantitative features. From the theropod sample found at Laño, seven morphotypes attributed to five taxa are identified: a medium to large abelisaurid (Arcovenator sp.) and ...

The first dromaeosaurid (Dinosauria: Theropoda) from the Lower Cretaceous Bayan Gobi Formation of Nei Mongol, China [PDF]

open access: yesPeerJ, 2015
The first dromaeosaurid theropod from the Lower Cretaceous Bayan Gobi Formation is identified based on an incompletely preserved partially-articulated left leg, increasing the known diversity of its understudied ecosystem.

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

open access: yesPeerJ, 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 ...

The endocranium and trophic ecology of Velociraptor mongoliensis

open access: yesJournal of Anatomy, Volume 237, Issue 5, Page 861-869, November 2020., 2020
We reconstructed the brain cavity and inner ear of Velociraptor to better understand its lifestyle and hunting abilities. We found brain structures that are present in modern birds, indicating an exceptional sense of balance and agility. The inner ear also closely resembles that of flightless birds, and Velociraptor had a similar hearing ability to ...

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

open access: yesPalaeontology, 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?

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

open access: yesДоклады 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.
