Loriolia echinoid Fossil
SITE LOCATION: Comal County, Texas, USA
TIME PERIOD: Lower Cretaceous (100-145 million years ago)
Data: Loriolia is a genus of extinct sea urchins from the Emiratiidae family. The Emiratiidae are a family of extinct sea urchins (Echinoidea) of the order Phymosomatoida. The Phymosomatoida are an order of sea urchins, found in Europe, North America, North Africa and the Middle East. They are distinguished from other sea urchins by the presence of large fused plates on top of the feeding lantern. The test is usually sculpted to some degree, but, unlike their close relatives the Temnopleuroida, the tubercles are never perforated. The opening in the test through which the anus passes, known as the periproct, is unusually large in sea urchins from this group. The apical disc, around the mouth, is only loosely attached to the rest of the test and is often missing in fossil species, giving the false impression that they also have a large oral opening
