Here we are delighted to present a highly important museum standard specimen Dyrosaurus crocodile and partial vertebrae with the reptilians teeth in their original placement in the alveoli (tooth sockets), within the upper and lower maxilla and mandible. All to often during the fossilisation process the animal's teeth are lost, damaged or severely weathered out of their sockets. This fine large specimen evokes the predatory nature of these vertebrates from the Cretaceous period, the condition is exceptional, the clenched jaws portray the character of this once fierce apex predator crocodile.
All too often these anatomical gems are discovered in an unarticulated and damaged condition, the mandibles separated as the bacteria in the muds which hold the decaying animal, devour cartilage and muscle tissues, allowing the bones to be scattered often by watercourse cutting through evolving fossil beds. This example must have been covered rapidly in heavy silts or mud's creating an anoxic environment. The lack of oxygen preserved the skeletal parts for perpetuity and allows us this unique glimpse back into the terrors of the Cretaceous period and prehistory when these giant gharial crocodiles patrolled the swamps and lagoon margins of the warm tropical Cretaceous of Africa.
The bone tissue from this Dyrosaurus, (like our other fossil crocodile specimens) now fossilised, is preserved exceedingly well, showing distinct, clear detail and texture around the muscle and sensory nerve attachment areas, note the scute, dermal plates rear of the skull with rippled or dimpled structure, this giving the crocodiles the archetypical leathery hide effect in life. This fossil has lots of characterful attributes, is a scientific study piece and forms an aesthetically pleasing display which could be a central statement fossil in a collection or used as a quirky interior design element.
The Tethyan phosphate trend sprawls across North Africa and up to the Middle East and the phosphate deposit is mined in several countries along the trend. The Moroccan portion of the trend is presently the most exploited, producing about 19 millions of tonnes, 14% of the global supply [1980 figures], making this one of Morocco main industries. All mining is state-owned by the Office Cherifien des Phosphates [OCP]. At and on the plateaux, in this region are 3 to 5 main outcrops of phosphate. Around the area of Kouribga, the Oulad-Abdoun plateau has been mined since the 1920's. The Ganntour plateau to the south has been mined for many years. A new mine in the central area of this deposit at Ben Guerir was commissioned in 1981. Hence the recent discoveries since this date of numerous fossils.
