Each animal built its own “apartment” or living chamber, and these were stuck together to make the colony. Some colonies grew like branches of a tree, with many living chambers on each branch. Graptolites are fossil colonial animals known chiefly from the Upper Cambrian through the Lower Carboniferous (Mississippian). The name graptolite comes from the Greek graptos, meaning "written", and lithos, meaning "rock", as many graptolite fossils resemble hieroglyphs written on the rock.

Plus the conditions of the actual planet back then, atmospheric content, climate would have had a huge impact on the type of life that would evolve.

genetically controlled in late Cretaceous dinosaurs. Studies on ultrastructure and palaeobiochemistry of egg shells and their organic matrix may also clarify many problems of taxonomic position of fossil egg shells from the Gobi desert and the bases of their teratology. This problem is very important for explanation of dinosaur extinction.

So far their fossils are more or less limited to the St. Lawrence Formation of Afton on the Minnesota side and Osceola on the Wisconsin side (with a stray report from the Reno Member of the Tunnel City … Sender: owner-dinosaur@usc.edu In my 1994 book, I placed graptolites and pterobranchs together in Class Pterobranchea, separate from acorn worms (Class Enteropneustea).

Graptolites are colonial animals that lived in all of the world's oceans from the Cambrian Period until the Carboniferous Period. The specimens we have for sale are from Morocco.
