Everything Dinosaur team members have created a new Achillobator giganticus scale drawing for use in their free Everything Dinosaur Achillobator fact sheet.  The fact sheet is being prepared as the new Beasts of the Mesozoic Achillobator figure is due in stock next month (July 2024).  This taxon represents one of the largest dromaeosaurs known to science. Whilst there has been speculation about whether the original fossil material belonged to more than one individual dinosaur, it is likely that the material does represent a single, individual animal.

Size estimates vary, but most palaeontologists suggest a total body length of between five and six metres. It was a robust dromaeosaur estimated to have weighed around three hundred kilograms.

Achillobator Scale Drawing

Achillobator (A. giganticus) was scientifically described in 1999 (Perle et al).  Although, the fossils were discovered many years earlier.  The fragmentary fossil material associated with this taxon comes from the Upper Cretaceous Bayan Shireh Formation of Mongolia.  It is difficult to date the fossil material precisely.  However, it is thought that Achillobator lived around 95 to 89 million years ago.  Therefore, Achillobator lived during the Late Cretaceous (Cenomanian to the Turonian faunal stage of the Late Cretaceous).

A spokesperson from Everything Dinosaur commented that there were two shipments of Beasts of the Mesozoic figures heading to the company’s warehouse.  One of these shipments contains the Achillobator figures along with the new Beasts of the Mesozoic Utahraptor figure.

The spokesperson added:

“It seems the design team are aiming to create articulated replicas of some of the largest dromaeosaurids known to science.  Both the Achillobator giganticus and the Utahraptor ostrommaysi are on the same shipment.  They should be in stock at Everything Dinosaur at the same time.”
