20864 - Lustrous Yellow Green Apatite Crystals on Feldspar Matrix - Imilchil (Morocco) KemKem_Beds_Fish_Assemblage Its morphology is never slightly

Its morphology is never slightly flat like that of the main species of Pterosaur

able to swim as well as walk on land

We also find in the Early Paleocene the genus Brachyopsemys tingitana

Incredible plate with seven specimens of this species in which three of them exceptionally preserve their antennae

20864 - Lustrous Yellow Green Apatite Crystals on Feldspar Matrix - Imilchil (Morocco) KemKem_Beds_Fish_Assemblage Its morphology is never slightlyApatite is a group of phosphate minerals, usually referring to hydroxylapatite, fluorapatite and chlorapatite, with high concentrations of OH, F and Cl ions, respectively, in the crystal. The formula of the admixture of the three most common endmembers is written as Ca10(PO4)6(OH,F,Cl)2.
