Lo Hueco en el 8th Meeting of the EAVP (2ª parte)

Otro de los trabajos de Lo Hueco que se presento en el 8th Meeting of the EAVP fue:

-Torices, A., Ortega, F. & Serrano, H. (2010). Presence of cf. Richardoestesia teeth in "Lo Hueco" (Upper Cretaceous, Cuenca, Spain). Abstract Volume 8th Annual Meeting of the European Association of Vertebrate Palaeontologists: 82

En este trabajo se documenta la aparición de un tercer morfotipo dentro de la diversidad de los dientes de un terópodo de Lo Hueco. Se tratan de dientes de pequeño tamaño (>1 cm de altura) y con una alta densidad de dentículos (>9 dentículos por milímetro en la carena distal) y que ha sido asignados tras diversas comparaciones a cf. Richardoestesia.

El resumen:

The theropod remains found in "Lo Hueco" site are composed mainly of theropod teeth and more scarce postcraneal material. Preliminary studies have disclosed the presence of two morphotypes. The characters that are present in the first and second morphotypes makes possible that the first morphotype can be attributed to Dromaeosaurinae and the second one to Velociraptorinae.
Here we discuss a third morphotype from Lo Hueco corresponding to small teeth, (>1 cm of heigh) and with a slightly biconvex general morphology. The denticles of this morphotype are small (> 9 denticles/milimeter in distal carina) with a square morphology. They have morphological and morphometric features similar to those of the teeth attributed to Richardoestesia in North America. They have been compared with a sample of teeth attributed to Richardoestesia gilmorei from the Royal Tyrrell Museum (Alberta, Canada) and their numerical data adjust perfectly with the ones from the North American sample. In Europe, teeth atributted to cf. Richardoestesia have been found in sediments from the Upper Jurassic of Portugal and the Lower Cretaceous of Cuenca in Spain. The measurements of these teeth and their morphological characteristics are compatible with this third morphotype. In the Upper Cretaceous it has been also described a tooth attributed to Richardoestesia. The density and morphology of the denticles of this latter is congruent with teeth described as similar to those of Richardoestesia, however this tooth is bigger than the described here. Taking these into account, we consider that this third morphotype can be attributed to cf. Richardoestesia.
