Named By: M. C. Langer, A. D. Rincón, J. Ramezani, A. Solórzano & O. W. M. Rauhut - 2014.
Classification: Chordata, Reptilia, Dinosauria, Saurischia, Theropoda.
Species: T. admirabilis (type).
Size: Tibia 25 centimetres long. Further details uncertain but total body length roughly estimated to have been about 1.5 meters long.
Known locations: Venezuela - La Quinta formation.
Time period: Hettangian of the Jurassic.
Fossil representation: Tibia (lower leg bone) and partial hip.
saw the first instance of a dinosaur genus being described as coming
from Venezuela. This genus was Laquintasaura,
a small plant eating
ornithischian dinosaur, fossils of which were discovered where a road
was being cut into the Venezuelan landscape. However, when
Laquintasaura was discovered, the teeth of small
were also found associated with it, hinting at a clue to a predator
prey interaction. Then later in 2014, a shin bone of a theropod
dinosaur was recovered and used to establish a new dinosaur genus;
Aside from the shin bone (technically known as a tibia), a partial hip found nearby was also assigned to the genus. Unfortunately we still don’t know a lot about what kind of theropod dinosaur Tachiraptor was, and this makes estimates of size and body form highly speculative in the absence of further fossil discoveries. Tachiraptor has however been loosely reconstructed to be about one and a half meters in length.
