Skorpiovenator
(Scorpion hunter).
Phonetic: Skor-pee-oh-ven-ah-tor.
Named By: Canale et al- 2009.
Classification: Chordata, Reptilia, Dinosauria,
Saurischia, Theropoda, Abelisauridae, Carnotaurinae.
Species: S. bustingorryi (type).
Type: Carnivore.
Size: Roughly estimated at about 6 meters long.
Known locations: Argentina - Huincul Formation.
Time period: Cenomanian of the Cretaceous.
Fossil representation: Almost complete specimen,
parts of fore limbs and tail missing.
This
large abelisaurid
roamed ancient Patagonia where it may have competed
with other predatory dinosaurs like the contempory carcharodontosaurid
Mapusaurus.
Skorpiovenator shares the same
characteristic short but
high skull morphology, and may not have had a large bite force, as has
been suggested for some other abelisaurids. Skorpiovenator
may have
used its deep skull as a 'club', arching its head back and swinging it
down onto its prey to drive the teeth home with enough force to do some
serious damage to its prey.
Even
though some parts of the fore limbs of the original specimen are
missing, they would have likely been reduced as they are in other
abelisaurids. For those not familiar with the abeilisauridae, or
especially the carnotaurinae group, the arms are so disproportionately
small that they make the arms of Tyrannosaurus
look big!
A
note about the name, Skorpiovenator did not
exclusively hunt scorpions,
it was named as such due to the large amount of scorpions present at
the dig site, a reminder that palaeontology starts outdoors in the
natural world. The species name S. bustingorryi is
in honour of Manuel
Bustingorry, who owned the land were Skorpiovenator
was discovered.
