Thanks for visiting!
Offered is a fascinating, well preserved and essentially complete 20cm (along axis) example of the freshwater semi-aquatic reptile Mesosaurus tenuidens, from the Lower Permian; Artinskian, Whitehall Formation, Ecca Group (Karoo) of western South Africa
A classic example of a freshwater species providing proof of Plate Tectonics, by occurring on both sides if the Atlantic Ocean, Brazil and West Africa, during the Lower Permian, before the Atlantic Ocean existed.
The skull and anterior spine are complete and recurved backwards, with the lower jaw intact, and needle-like teeth visible anteriorly under magnification. The complete vertebral column right to the tip of the tail is articulated, except for a short curved portion, absent due to a natural joint, and the tail lies sub-parallel to the main spine.
The rib cage is replete with all ribs and all four limbs are in evidence; two replete with digits, and both the pectoral and pelvic girdles are evident and best examined under magnification.
In all a fascinating and displayable legacy of Early Permian freshwater life, pre-dating the tectonic opening of the Atlantic Ocean.
AFFORDABLE price for such a complete, exceptional example........... one for the serious collector!.
Although I sell a very wide range of fossils from Pre- Cambrian to Pleistocene age, I specialize in trilobites from all over the globe and in particular, British species.
I collect regularly in the UK, with more than forty five years of fieldwork experience and probably the best working knowledge of British trilobite localities. I have a doctorate and a masters degree in trilobite taxonomy and British Palaeozoic stratigraphy and an Open University degree in Natural Sciences.
If you are an amateur collector, a more serious scientific collector, or an agent for an educational organization ( e.g College, University or Museum), I can supply materials to suit your needs! I also buy whole collections and trade materials too. Visits are welcome,by appointment only.
