(Alberto) Garrido (discoverer)'s Auca (Mahuevo) lizard.
A. garridoi was discovered during 1999 and is 70% the size
of the Carnotaurus sastrei holotype specimen, it is described as the
most complete abelisaur skeleton ever collected. The arms are
proportionately larger than those of Carnotaurus, the skull is longer and lower and has bumps instead of the
horns seen in Carnotaurus. The specimen preserves impressions of
soft tissue around the pelvic region.
The specimen had been buried at the bottom of a shallow lake;
because part of its skull was broken apart, the describers suggest
it may have been involved in a fight and killed when another
dinosaur bit or struck its head, the exact cause of death remains
uncertain. |
