Paleozoo Placoderm Groenlandaspis

[Paleozoo]

Groenlandaspis - a Paleozoo evolutionary model.

Groenlandaspis is an extinct placoderm of the Middle to late Devonian period (370 - 360 ma).
It is a member of the order Arthrodira (gk. jointed neck) and it had a distinctive thoracic shield with a
pyramid-like peak that would have helped it plane through the water column.

Although most of its bony plates were fused together and rigid, the nuchal gap would have allowed for
some movement between the thorax and head.  This anatomical feature allowed many Arthrodiri to develop
large bites but Groenlandaspis is not thought to have been a predator as its mouth parts were quite small. 
However it would have been an adept swimmer and was probably a far-ranging seabed scavenger as its
remains have been found right around the world, most notably in Greenland and Australia.

Initially the armour plating of the placoderms was probably used as a form of defence against other predators, such
as the large arthropods that dominated the Silurian seas, but once the Arthrodire's 'jointed neck' became combined
with an articulated jaw, placoderms quickly became formidable predators in their own right.

Paleozoo aims to provide an outline of Palaeozoic evolution - expressed in a series of short
animations and a collection of museum-grade lifeform models.

Beautiful work. Any hints as to what might be in the pipeline?

[Paleozoo]

Mmmm...lots

Sarcopterygian, Ichthyostega, Dimetrodon, Gorgonopsid, Lystrosaurus, Tully Monster, Phacops, Pterygotus, Marrella.......

The list goes on. It's all solo work though and each creature includes animation, so its all very slow.

I'd snap a lystrosaurus out your hands in a blink.

[BlueKrono]

I'd go for all of those pre-amphibians.

Thanks very much! Looking forward to seeing them.
