Gerastos is a genus of trilobite in the order Proetida that lived between the Pragian and Eifelian of the Lower-Middle Devonian

The complicated sedimentarian architecture of the layers where most large vertebrates are found makes the excavation methodology a real challenge

05279 - Fully Complete NWA L-H Type Unclassified Ordinary Chondrite Meteorite 8.9g Tetragramma Gerastos is a genus ofThese meteorites were found in the Saharan Desert in Northwest Africa, likely by nomads. In order to classify them it would be necessary to cut off a section for analysis. Although they are exceedingly rare when compared to terrestrial rocks, these are the most abundant type of meteorite and are referred to as common chondrites. H and L (designating the amount of metal contained) type chondrites have been already extensively studied. Composed largely
