Estemmenosuchus Scale Drawing

One of the new 1:20 scale figures from CollectA for 2018 is a model of the Dinocephalian Estemmenosuchus.  We are not expecting this model to arrive in stock until the middle of this year, but we are busy preparing a fact sheet to accompany sales of this Permian herbivore (most scientists state that these animals were plant-eaters).  For virtually every named prehistoric animal model we sell, we include a fact sheet about that animal in with the customer’s order.  Along with the fact sheet, we also provide a handy scale drawing so that readers can see at a glance just how big this prehistoric animal was.

Deciding on Which Species of Estemmenosuchus to Depict

There are currently two species of Estemmenosuchus recognised, Estemmenosuchus mirabilis and the much larger Estemmenosuchus uralensis, but which species does the CollectA Deluxe 1:20 scale figure represent?  The CollectA model is over seventeen centimetres long and at 1:20 scale this represents an animal around 3.5 metres long.  This suggests that the model is getting towards the larger E. uralensis, which measured between 3.5 and 4.5 metres in length.  However, the larger Estemmenosuchus uralensis only had one pair of horny projections on the skull, whilst the smaller of the two recognised species E. mirabilis, had two pairs of horns on the top of the skull.

There are other anatomical differences too.  The skull of the larger species Estemmenosuchus uralensis was up to fifty percent longer.  The muzzle of E. mirabilis is proportionately smaller, but wider towards the front (anterior portion), there are also subtle differences in the morphology of the skulls, although both species show the characteristic thickened bone which is so reminiscent of the estemmenosuchids.  Based on this information, we think that the new for 2018 CollectA Deluxe Estemmenosuchus represents the smaller of the two valid species (E. mirabilis).  Our scale drawing has therefore been prepared based on an animal measuring around three metres in length and weighing an estimated 750 kilograms.
