Tachiraptor admirabilis: New Carnivorous Dinosaur Unearthed in Venezuela

Paleontologist Dr Oliver Rauhut of the Ludwig-Maximilians-University in Munich, Germany, and his colleagues have described a new dinosaur genus and species that lived in what is now Venezuela during the earliest part of the Jurassic period, about 201 million years ago.

The newly-discovered dinosaur is a small bipedal theropod, with an estimated body length slightly over 1.5 meters.
It belongs to a sister group of Averostra, a large clade of theropod dinosaurs that is known primarily from the Middle Jurassic.
The paleontologists found only two fossilized bones of the new dinosaur in the La Quinta Formation, about 4 km northwest of the town of La Grita in Táchira, Venezuela.
They named the new genus and species – Tachiraptor admirabilis.

“The genus name tachiraptor derives from Táchira and raptor (Latin for thief), in reference to the probable predatory habits of the animal,” the team explained in a paper published in the journal Royal Society Open Science.
“The specific name admirabilis honors Simon Bolivar’s ‘Admirable Campaign,’ in which the town of La Grita played a strategic role.”
Tachiraptor admirabilis probably preyed upon any smaller creature it could catch, including a recently discovered plant-eating dinosaur called Laquintasaura venezuelae.
