A highly important museum Dyrosaurus crocodile skull and partial vertebrates and 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 and very large specimen skull evoke the predatory nature of the vertebrates of the Cretaceous period. The condition is exceptional, the clenched jaws portray a character of this once fierce apex predator.
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 watercourses 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, a time when these giant gharial crocodiles patrolled the swamps and lagoons and margins of the warm tropical Cretaceous of Africa.
The bone tissue from this Dyrosaurus, (like our other fossil crocodile specimens) now fossilised, and preserved, exhibiting distinct detail of the texture around the muscle and sensory nerve attachment areas. The fossil crocodile skull has lots of characterful attributes, is a scientific study piece and a complementary aesthetically pleasing display statement which could be a central feature 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 with the trend. The Moroccan portion of the trend is presently the most exploited, producing about 19 million 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 1920s. 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.
The Dyrosaurus crocodile skull and vertebrae</a> contained within the original burlap field jacket. An important and rare discovery, the museum standard fossil crocodile mandibles and skull were unearthed completely articulated, that is with the teeth and bones of the ancient reptilian in the positions got their enatomy, within the upper maxilla and lower mandible. All too often during the fossilisation process the teeth are loosened, damaged, severely weathered or lost; to find an intact skull like this is a rare event.
