07038 - Nice Halisaurus arambourgi (Mosasaur) Partial Maxillary Bone in Matrix Cretaceous Silicified Pine Cones The rostral barbs of this

The rostral barbs of this enormous sawfish are relatively common in the Cretaceous quarries in the South of Morocco

The last feature makes a significant difference in relation to teeth of the genus Liodon Agassiz

Mader & Kellner (1999) (Full reference: B

The teeth which are found on the surface in nearby sites have a bad preservation due to the abrasion that they suffer during its exposition to high temperatures and aggressive desert climate conditions

It is preserved in full and almost perfect

07038 - Nice Halisaurus arambourgi (Mosasaur) Partial Maxillary Bone in Matrix Cretaceous Silicified Pine Cones The rostral barbs of thisPrecious premaxillary specimen preserved in its natural matrix. It has small glued and tiny filled fractures. This specimen has been stabilized on its surface by Paraloid B 72 to ensure its stability and consistency. This process does not affect neither the color nor any of the characteristics. It simply makes the specimen better preserved in the long term. In the international market is very common to find Mosasaurus rests coming from the phosphate
