Scientific name: Acanthostega sp.
Class: Tetrapoda
Age: Upper Devonian
Size: 50-70 cm long
Location: Greenland
Description
Palaeoartistic reconstruction of the well-known transitional fossil It is considered a transitional fossil of the process of the conquest of the terrestrial environment by vertebrates.
It was over half a metre long and, like other primitive tetrapods, it combined gills and lungs; it had long limbs ending in eight fingers.
The limbs lacked wrist and ankle joints, and, consequently, it is believed that they were too weak to support their weight out of water; for this reason it must have spent almost all its life in it, using its legs as oars to move around.
The model in the photo is not in stock. Due to its artistic nature, the models will not be exactly the same. It is made to order.
