Description
Schizorhiza Stormeri is a Cretaceous cartilaginous Fish, and is unique among all "saw-snouted" Elasmobranchii, the rostral teeth are unique in comparison in that they did not fall off as they are replaced. Rather, they remain in place, with the new teeth under them, until they are worn off. Thus, the rostrum's edge had a continuous serrated cover of tooth enamel. Full-grown rostral teeth measured less than in other Sclerorhynchoidea, let alone sawfishes, at 1-2 cm tall and 4-8 mm wide.
Schizorhiza fossils have been found in northern and central Africa, Iraq, Italy, Texas (USA), Coahuila (Mexico) and Bolivia.
The S.stormeri reached a length of about 1.5 meters. Its habitat was apparently shallow or epicontinental seas, as evidenced by its associated fauna, the cartilaginous fish Pseudocorax, Scapanorhynchus texanus and Serratolamna serrata, and the molluscs Cymprimera, Ethmocardium, Eutrephoceras, Platyceramus vanuxemi, Sphenodiscus and Turritella vertibroides.
Condition Report
Very few Fossil blocks are ever found of this particular specie, especially in this condition due to the delicate Teeth, and Roots.Large assemblage of Teeth; which suggests that all these Tetth came from the Same Animal.
A unique specie, and unlike other common types of shark/sawfish of this era
Exceptional preservation, the Teeth/Crowns (which can be seen) still maintain their original Roots, which is quite fascinating, as it is incredibly rare occurrence from this location.
The Group of 14 teeth [it is possible more may be entombed within the block]. Good size and colour, with excellent patina to the enamel [glossy]. Professionally cleaned off for display in the field in North Africa>
