Dinheirosaurus lourinhanensis, a new diplodocid from Portugal



           There is a new diplodocid dinosaur in Lourinhã (Upper Jurassic of
Portugal).

            The ref is:
BONAPARTE, J.F. & MATEUS, O. (1999). A new diplodocid, Dinheirosaurus
lourinhanensis gen. et sp. nov., from the Late Jurassic beds of Portugal.
Revista del Museo Argentino de Ciencias Naturales. 5(2): 13-29.

        And the abstract is:
        Presacral vertebrae of a new Diplodocidae from the Late Jurassic
Amoreira- Porto Novo Formation f Lourinhã, Portugal are described and
figured. Dinheirosaurus lourinhanensis g.et sp. nov. is diagnosed by well
developed accessory articulations derived from the hyposphene, exposed in
lateral view; and by the smaller dorsoventral length of the lower section of
the neural arch. It is considered that the organisation of the dorsal neural
arch of Dinheirosaurus is more derived than in Diplodocus, except in the
dorsoventral development of the lower portion of it, which is higher (more
derived) in the latter. Possibly the isolated geography of Portugal in the
Late Jurassic gave rise to the distinct characters of this new genus.
