Dinosaur Genera List corrections #161



This email just in:

A new Spanish sauropod has been described.

It comes from the "Arenas y arcillas del  Collado Formation", previously
regarded as Lower Cretaceous "Weald facies" and now assigned to the
Jurassic-Cretaceous boundary "Purbeck facies".

It is related to the group formed by (Barosaurus + Diplodocus) + 
Dicraeosaurus.

Other dinosaurs described from the Collado Formation are two spatulated
teeth of Sauropoda indet., a tooth of Theropoda indet.,  and postcraneal
remains of the stegosaur _Dacentrurus armatus_.

Ther ref is:

Casanovas, M. L., Santafe, J. V. & Sanz, J. L. 2001. _Losillasaurus
giganteus_, un nuevo sauropodo del transito Jurasico-Cretacico de la cuenca
de "Los Serranos" (Valencia, España). Paleontologia i Evolucio, 32-33:
99-122.

The paper is in spanish, and the abstract provided by authors is the 
following:

        "The Late Jurassic-Early Cretaceous site of La Cañada (Barranco de
Escaiz, Losilla. Aras de Alpuente, valencia) has delivered several pieces
of a new Sauropod Dinosaur called _Losillasaurus giganteus_.The material
includes a cranial fragment, several vertebral fragments and complete
cervical, dorsal, sacrae, and caudal vertebrae; appendicular skeleton
(humerus, ulna, radius, metacarpal); sternal plates; and pelvic elements
(ilium, ischium and pubis).
        The diagnosis of _Losillasaurus giganteus_ is based on two
autapomorphies and singular combination of synapomorphies. The two
autapomorphies are: neural spine of the anterior caudal vertebrae with a
lateral enarded outline in dorsal view (cutlass-like shape). Moreover, the
value of the relationships between the anterior-posterior dimension of the
neuroapophyseal base with respect to the total highness is around 0,5"
