Subject: "Aniksosaurus darwini"
To the listing of discoveries that was added, in
1995, aniksosaurus darwini 130 kilómertos to the north of Sarmiento. Martinez
said that " the anatomy of these fossils does not call so much to the
attention. It seems great dinosaurio carnivorous but dwarfed. What would be
possible is that outside a species located near the base of the great group of
dinosaurios that in the long run went to give origin to the birds. This animal
would be tetanuro but it would have a series of characteristics that already
preanunican to the evolved group more ".
This gives us some new information regarding
"Aniksosaurus". First, we have a species name, "A. darwini".
Second, we have a location- 130 km north of Sarmiento, Brazil. Third, we
can guess the formation. What other species is described in the
article as having been found 130 km north of Sarmiento?
Notohypsilophodon comodorensis, which was found in the Bajo Barreal
Formation. What else is mentioned in the article? Xenotarsosaurus
bonapartei, Epachtosaurus scuttoi and a titanosauriform skull, all from the
same formation. Thus, I conclude "Aniksosaurus" was found in that
formation as well. What else do we know? It's a tetanuran and
"near the base of the great group of dinosaurios that in the long run went to
give origin to the birds". This sounds suspiciously like "basal
coelurosaur" to me. Finally, the real link to official data. Are
there tetanurans known from the Bajo Barreal Formation already? There
are two, a Megaraptor relative (Martinez, Lamanna, Smith, Casal and Luna 1999)
and a basal coelurosaur (Martinez and Novas 1997). Guess which I think
"Aniksosaurus" is. So, for further information on "Aniksosaurus", read
Martinez and Novas (1997), which can be found translated on Polyglot.
Finally, some concrete information on this nomen nudum.
