Trilobites are marine creatures. This means that their main habitat is the water. They were found in deep seas, on the sea beds, in the open ocean, in shallow waters and rivers. They lived over 250 million years ago when the oceans were far more widespread than we know them today. Hence, Trilobite fossils can be found across the world on almost ...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.
