Science Category - A Review of the Collecta 1:40 Scale Dacentrurus ...

Collecta?s range of prehistoric animal models gets to twenty with the introduction of this new model of the European Stegosaur Dacentrurus (Dacentrurus armatus).

The name European Stegosaur Dacentrurus (Dacentrurus armatus) means ?well armoured very pointy tail? an apt description for this large herbivore as scientists believe that for the most part, it had pairs of spikes running down the length of its body and tail. There were also very probably two prominent defensive spikes over the shoulders and the tail was tipped with an array of sideways pointing spikes, some of which were more than a metre long. It would have taken a very brave (or desperate) Theropod dinosaur to tackle a fully grown Dacentrurus, there must have been easier ways of getting a meal in the Late Jurassic.

A Brief History of Dacentrurus

This dinosaur is known from several fragmentary fossil remains that have been found in Europe (England, France, Spain and most recently Portugal). Most palaeontologists estimate that this Stegosaur was about 6 to 8 metres long, but the discovery of a 1.5 metre long pelvis that has been ascribed to this genus, suggests that this dinosaur could have reached lengths of up to 10 metres. This would make Dacentrurus one of the largest members of the Stegosauria. The fossils suggest that this dinosaur had a range of both advanced and primitive features, making it an unusual member of this diverse group of dinosaurs. It was formally named and described by Richard Owen, the English anatomist and scientist (later knighted) in 1875, making it the first Stegosaur to be scientifically described. However, the name given by Owen ? Omosaurus (meaning stumpy fore-limbed lizard), was already occupied in scientific literature as a type of prehistoric crocodile had already been given that name. The American zoologist Frederic Augustus Lucas carried out a review of the then known scientific data and assigned the fossil material to the genus Dacentrurus in 1902.

The New Collecta Dacentrurus Model

The Collecta Dacentrurus model measures 29 cm long and as it is posed rearing up on its hind legs it stands nearly 17 cm tall. To show the dinosaur?s estimated size, this model comes with a plastic model of a man, this provides an excellent scale reference.

The replica is painted light brown with darker patches of brown along the flanks. The skin texture is excellent and individual pieces of dermal armour can be seen depicted along the tail and legs. The fact that this Stegosaurus is depicted in a rearing stance makes this replica from Collecta highly unusual and therefore we suspect it will become a favourite amongst dinosaur models collectors.
