Ammonita model - a sub -party of extinct cephalopods (cephalopoda). Their shells occur in the rocks of maritime origin from the period from Dewon to the end of Cretaceous.
The model is best printed in the resin. It has no scale - print in the size you need. Two variants - with body and tentacles and with an empty shell. The Amo-ALL file has a dense mesh, if you have a problem with it, use AMO1 and AMO2
