Re: [dinosaur] Ubirajara, new compsognathid theropod with a filament "mane" from Lower Cretaceous of Brazil



A further update...


The Sociedade Brasileira de Paleontologia [Brazilian Society of Paleontology] has formally requested that Cretaceous Research remove the Ubirajara paper from the website and "withhold a printed version until a legal investigation on the legal status of the fossil is concluded"... The journal has agreed to pull the paper for now.

Quick Google translate version in part:

In fact, the authors of the Cretaceous Research article were not aware that, even with a DNPM authorization, the export of Brazilian fossils would still be illegal if it were not also supported by authorization from CNPq (Conselho Nacional de Scientific and Technological Development). This is clear in Ordinance No. 55, of March 14, 1990, from the Ministry of Science and Technology. Furthermore, this same legislation establishes that all fossil-type specimens, as is now the case with SMNK PAL 29241, must remain in the country.

As such, SBP is pleased to let people know that the editors of Cretaceous Research considered temporarily withdrawing the ScienceDirect manuscript and, most importantly, suspend its printed publication, until the issues are properly addressed.Â

Discoveries of dinosaurs with integumentary structures over the last few decades have revolutionised our understanding of the phylogenetic relationships between birds and dinosaurs as well as the origin and evolution of feathers. A remarkable number of dinosaurs have been discovered with a diverse range of preserved integumentary structures. Several of these dinosaurs are adorned with elaborate integumentary structures that have been linked to behaviours including thermoregulation, egg incubation, and sexual display. Among Theropoda, such elaborate structures have only been previously recorded within Maniraptoriformes. However, elaborate monofilamentous structures are also present in some small ornithischians. The majority of theropods preserving integumental structures come from the Upper Jurassic and Lower Cretaceous of China or the Upper Jurassic of southern Germany, and all are of Laurasian origin. Herein, we describe a new genus and species of compsognathid theropod from the Lower Cretaceous (Aptian) Crato Formation of Northeast Brazil, representing the first Gondwanan non-avian theropod with preserved filamentous integumentary structures. It is also the first non-maniraptoran possessing elaborate integumentary structures that were most likely used for display. These include slender monofilaments associated with the base of the neck, increasing in length along the dorsal thoracic region where they form an impressive mane, as well as a pair of elongate, ribbon-like structures likely emerging from the shoulder. Such elaborate integumentary structures are hitherto unknown in any other dinosaur, although superficially similar elongate display feathers emerge from the carpal region of the male standardwing bird-of-paradise (Semioptera wallacii).
