Name

Tarascosaurus ‭(‬Tarasque lizard‭)‬.

Phonetic

Tah-ras-coe-sore-us.

Named By

Jean Le Loeuff‭ & ‬Eric Buffetaut‭ ‬-‭ ‬1991.

Classification

Chordata,‭ ‬Reptilia,‭ ‬Dinosauria,‭ ‬Saurischia,‭ ‬Theropoda,‭ ‬Ceratosauria,‭ ‬Abelisauridae‭?

Diet

Carnivore.

Species

T.‭ ‬salluvicus

Size

Preserved‭ ‬length of holotype femur‭ ‬22‭ ‬centimetres which accounts for a reconstructed length of‭ ‬35‭ ‬centimetres when complete.‭ ‬Scaling this to generic abelisaurid theropod‭ ‬dinosaur‭ ‬proportions results in reconstructed estimate of‭ ‬2.6-2.7‭ ‬meters long for the holotype individual

Known locations

France -‭ ‬Fuvelian Beds.‭ ‬Spain.

Time Period

Campanian of the Cretaceous.

Fossil representation

Fragmentary remains,‭ ‬including upper femur and‭ ‬2‭ ‬caudal‭ (‬tail‭) ‬vertebrae.‭ ‬Further remains from Spain have been attributed to the genus.

In Depth

       Despite its appearance in dinosaur documentaries like‭ ‬Dinosaur Planet‭,‭ ‬not much is known about Tarascosaurus.‭ ‬The type material is very incomplete but has still seen this dinosaur tentatively placed within the Abelisauridae.‭ ‬Aside from Betasuchus,‭ ‬Tarascosaurus is the only representative of this group of theropod dinosaurs which were previously considered to be present only in the southern continents and absent from Europe.‭ ‬Indeed not all palaeontologists are convinced about the placement of Tarascosaurus with the abelisaurs.‭ ‬Most of the renditions of Tarascosaurus are based upon much more complete abelisaurid genera like Aucasaurus.

       Tarascosaurus was named after Tarasque,‭ ‬a legendary dragon once said to live in Provence.‭ ‬Since this time the names of other legendary European dragons have been used to name genera of prehistoric creatures,‭ ‬one example being Smok that was named for a dragon in Polish mythology.
