The Spanish Megalosaurid is an unnamed genus of extinct megalosaurid theropod dinosaur from Kimmeridgian stage of Late Jurassic Asturias, Spain.
Description[]
Jurassic footprints with a weak mesaxony and probably related to very large or giant megalosaurid theropod trackmakers. Photographs by José-Calros García-Ramos.
The theropods remains are highly fragmentary; the remains are an isolated anterior caudal vertebra, as well as the largest theropod tracks found.
The caudal vertebra can be shown to represent a megalosaurine megalosaurid and represents the largest known identifiable theropod skeletal remain described from Europe so far, albeit the largest size estimations are potentially contested by the available Vectispinus remains.
The tracks attributed to this particular theropod are also amongst the largest theropod footprints reported from any setting and can be assigned; one being characterized by its robustness and a weak mesaxony, and the other characterized by a strong mesaxony, representing a more gracile trackmaker.
The notable robustness of megalosaurine megalosaurids fits well with the described robust morphotypes. The remains are also represent that this group of theropods ( megalosaurine ) were much more common throughout all of the Europe; far much more common than previously recognized. Meanwhile other groups like allosauroids seem to be represented by allosaurids in Western Europe and metriacanthosaurids in more eastern areas.
