Trilobites are the most diverse group of extinct animals pres

It is quite interesting that the first trilobite found in Morocco, below even the fallotaspidoids, is a suture-bearing bigotinid, Hupetina antiqua. This potentially complicates the idea that the first trilobites were sutureless, and their descendents evolved sutures. Others have speculated that only a small fraction of Morocco's available trilobite resources have yet to be explored, and that while some quarries that were first mined back in the '80s have now been virtually tapped out, new locales are being discovered on an annual basis.3 Şub 2021 ...
