1498 - Museum Grade Spinosaurus aegyptiacus Dinosaur Complete Toe Finger with Claw- KemKem Beds

Scientific name: Spinosaurus aegyptiacus - Toe Finger

Location: Taouz, South Morocco

Geological Formation:  Ifezouane Fm

Age: Upper Cretaceous, Cenomanian stage ( 96 million years)

Size:  Claw: 10,4cm - 1rt Phalanx: 15,5cm - 2nd Phalanx: 8cm 

Ref: 1498

Observations: Incredible nice huge complete toe finger. Each of the bones belong to different individuals, but of the same size. This is an exceptional piece, with a high quality claw without restorations, just few glued fractures. Only some of the phalanges have some glued and filled fractures.

The different Geological Formations that make up the orography of the Cretaceous in the South East of Morocco have been mostly treated in an undifferentiated and not too accurate way by collectors, by Paleontology aficionados and by fossil dealers.

Historically, fossils dealers from all around the world have identified the dinosaur pieces from this sector as belonging to the Tegana Formation. However, in a formal way, most of the last published studies refer to other nomenclature in the description of the units and formations of the Lower and Upper Cretaceous.

That's why next we include an interesting link where the Aoufous Formation and the Ifezouane Formation are described, making reference to their age, geological history, sedimentology, stratigraphy and vertebrate assemblage. It includes a brief explanation of the stratigraphic concepts that have been established formally until today in the studies of this sector of Morocco.

This way, the precise stratigraphic understanding of the origin of the rests, as well as the sedimentological analysis, enables a better paleoecologic characterization of the environments where this amazing dinosaur assemblage lived.
