Étymologie Héros Achille

Achillobator est un genre fossile de dinosaures théropodes du Crétacé supérieur ayant vécu dans l'actuelle Mongolie. C'était un carnivore bipède possédant une grosse griffe en forme de faucille sur le deuxième orteil de chaque pied arrière. Il s'agissait d'un grand dromaeosauridé mesurant entre 4,60 et 6,60 mètres, du museau au bout de la queue.

Skeletal diagram featuring the size and known elements from the holotype of the large dromaeosaurid Achillobator giganticus. Being a member of the largest dromaeosaurids ever (Austroraptor, Dakotaraptor and Utahraptor), its remains were discovered in Burkhant, Mongolia, from the Bayan Shireh Formation in 1989, and later described in 1999; however, in a very obscure and preliminar paper.[1] The holotype of Achillobator, MNUFR-15, is fragmentary, consisting of a left maxilla preserving nine teeth and two alveoli, four cervical vertebrae, three dorsal vertebrae and eight caudal vertebrae, a nearly complete pelvic girdle compromising both pubis, right illium and right ischium, both femur and left tibia, left metatarsals III and IV, manual and pedal phalanges with some unguals, right scapulocoracoid, an isolated radius, two ribs and caudal chevrons. Traces of tail tendons were found too, but mostly isolated.[1] Although fragmentary, it is more complete than the respective holotypes of Austroraptor, Dakotaraptor and Utahraptor. It was found as an associated, but overall disarticulated individual, however, it is known that some elements were found in semi-articulation[2], refuting a chimera hypotesis, as proposed by Burnham et al. 2000.[3] The missing elements were restored after close relatives like Utahraptor, Saurornitholestes, Dromaeosaurus and Deinonychus. Most estimates give Achillobator 5 to 6 m (16.4 to 19.7 ft)[1][2][4][5], in this case, the axial length ended up in 5 m (16 ft).
