Team members at Everything Dinosaur are busy preparing for the arrival of the new Beasts of the Mesozoic figures. They are wave three of the tyrannosaur series and the new figures will include the Asian tyrannosaur Alectrosaurus (Alectrosaurus olseni).

The new tyrannosaur figures include:

  • Eotyrannus lengi
  • Moros intrepidus
  • Albertosaurus sarcophagus
  • Gorgosaurus libratus
  • Daspletosaurus torosus
  • Tarbosaurus bataar
  • Alectrosaurus olseni

Alectrosaurus olseni

Alectrosaurus is known from hindlimb fossils and fragmentary elements of the hips. Much of the ascribed fossil material was discovered during the Third Asiatic Expedition to Inner Mongolia (China), by the American Museum of Natural History. It was formally described in 1933 (Gilmore).

The fossil material came from deposits associated with the Iren Dabasu Formation. The age of the strata remains uncertain. Relative dating using the abundant ostracod fossils suggest a Late Campanian to Maastrichtian age. However, the vertebrate assemblage represents fauna that indicate that the deposits are much older perhaps dating from the Turonian faunal stage. This would suggest that Alectrosaurus lived around 90 mya (million years ago).

The size of Alectrosaurus olseni is unknown. Its body length has been estimated at between five and six metres. Analysis of the limb bones and their ratios (femur to tibia), indicate that this dinosaur was a fast runner. It was probably a pursuit predator. The weight of A. olseni has been estimated to be around six hundred kilograms.

An Everything Dinosaur Scale Drawing

As part of our preparations for the arrival of the new Beasts of the Mesozoic tyrannosaurs, we have commissioned an Alectrosaurus scale drawing. This illustration will be incorporated into the free fact sheet that we will send out with the Alectrosaurus olseni model.
