Re: [dinosaur] Riabininohadros and additional ornithopod material from Upper Cretaceous of Crimea (free pdf version found)




After some additional checking on Russian websites, I found a similar but shorter paper by the same authors that has a free pdf this time:

A.V. Lopatin & A.Ð. Averianov (2019)
On the findings of dinosaurs in the Crimea.
Proceedings of Higher Educational Establishments. Geology and Exploration 2019 (1): 67-71. (In Russian)

Ornithopod dinosaur Riabininohadros weberae from the Upper Cretaceous (upper Maastrichtian) of the Crimean Peninsula (Besh-Kosh) shows a set of primitive characters of hind limbs observed in iguanodontids and basal ornithischians and is referred to as Styracosterna indet. The second dinosaur specimen from Crimea (Aleshino) is a fragmentary skeleton, including cervical and dorsal vertebrae. It possibly belongs to advanced iguanodontids or primitive hadrosauroids. Thus, in the Maastrichtian of the Crimean Peninsula, at least two dinosaur species coexisted.

A new paper in Russian (English translated version not yet posted):

A. O. Averianov & A. V. Lopatin (2019)
Dinosaur remains from the Upper Cretaceous of Crimea.
Paleontological Journal 2019 (53)(4): 73-86 (Russian edition)
DOI: 10.1134/S0031031X19040020

A new study of the holotype of Riabininohadros weberae from the Upper Cretaceous (upper Maastrichtian) of Crimea (Besh Kosh) revealed previously unknown fragments of femur, astragalus, and calcaneus. This taxon is characterized by a complex of primitive characters found in Iguanodontia and basal Ornithischia and its phylogenetic position can be defined as Styracosterna indet. The second dinosaur record from Crimea (Aleshino) is represented by a fragmentary skeleton, including cervical and dorsal vertebrae. It may belong to a derived iguanodontian of primitive hadrosauroid. Thus, at least two species of dinosaurs coexisted in the Maastrichtian of Crimea.
