Exposures of Cambridge Greensand may also be present in each Cambridgeshire and neighbouring Hertfordshire. It’s well-known for pterosaur fossils. Over 200 pterosaur fossil bones were discovered, despite the fact that they’re fragmentary.  Those fossils constitute pterosaurs (most commonly ornithocheirids) that died out at sea.  Their bones had been buried at the seafloor simplest to be exhumed once more by means of historic storms and redeposited as a part of geologically a lot more youthful strata.  In spite of their deficient situation and extremely fragmentary nature, nineteenth century scientists erected a large number of pterosaur taxa.

An instance of a doubtful Cambridge Greensand ornithocheirid is Criorhynchus.

Fragmentary fossils of large pterosaurs from the Cambridge Greensand.

Many genera of pterosaur were erected from extremely fragmentary stays related to Cambridge Greensand subject material. An instance is the ornithocheirid “Criorhynchus”. There may be a lot debate whether or not it is a legitimate genus or a nomen dubium. Image credit score: The entirety Dinosaur.

Criorhynchus and the Cambridge Greensand

Staff individuals at The entirety Dinosaur got the chance to view Cambridge Greensand pterosaur fossils while visiting the Sedgwick Museum of Earth Sciences (Cambridge).  Most of the labels related to the fossilised bones discuss with Criorhynchus.  The validity of this taxon has been wondered.  It’s an instance of a taxon being erected according to poorly preserved and scrappy fossil stays.  Greater than part a dozen Criorhynchus species had been named, all according to Cambridge Greensand subject material. The debate over the validity of the pterosaur genera erected according to fossils from this geological unit continues.

The Ornithocheiridae had been geographically standard. Their fossils were present in Asia, Australia, Europe and the Americas. Then again, organising the taxonomy of the Ornithocheiridae because of the nineteenth century analysis continues to stay problematic.  It’s nonetheless attention-grabbing to talk over with museums that experience those fossils of their collections.  While maximum researchers overlook a large number of the Cambridge Greensand pterosaur fossils, they constitute the most important bankruptcy within the find out about of the outstanding Pterosauria.
