Barco, J.L. 2006. New data on Therangospodus oncalensis from the Berriasian Fuentesalvo Tracksite (Villar del R?Âo, Soria, Spain): an example of gregarious behaviour in theropod dinosaurs. Ichnos 13(4):237-248
Abstract: Therangospodus oncalensis is a Berriasian theropod ichnotaxon from the Cameros Basin (Soria Province, Spain). We discovered new trackways assigned to this ichnotaxon during cleaning and conservation works at the type locality (Fuentesalvo), enabling us to describe it more precisely.
Therangospodus oncalensis was made by a medium-sized theropod dinosaur and is characterized by a single tapering pad on each toe, a rounded heel impression and a narrow trackway. In addition to having similar morphometric characteristics, most of the trackways at the Fuentesalvo site show comparable size and biometric features. This indicates that, in terms of size and age, a homogeneous population of a single theropod species could have produced these tracks.
Moreover, the similar orientation (lying within a range of only 15Ă°) and estimated speed suggested by most of the trackways, lend weight to the hypothesis that the trackmaker of Therangospodus oncalensis was able, at least at times, to move in structured packs displaying gregarious behaviour. Furthermore, this is the first structured pack of theropods to be described.

Trzeba siÄ niestety przyzwyczajaÄ. Angielski we wspĂłĹczesnej paleontologii jest niezbÄdny. Ostatnio jednak siÄ dowiedziaĹem, Ĺźe jak ktoĹ chce siÄ zajÄ Ä mongolskimi dinozaurami to przyda mu siÄ cyrylica - mnĂłstwo publikacji na ten temat powstaĹo w jÄzyku rosyjskim W koĹcu Rosjanie siedzieli w Mongolii od dawna...Dominik pisze:Wypada??oby to przet??umaczyĂ? - na stronĂ? trafia coraz wiĂ?cej angielskich news??w
