Fossil sea sponge

Caption. Evidence of early sponges was found in these sediments in Oman, a Marinoan age (about 635 million year old) rock unit of calcium carbonate deposited on rocks of glacial origin. The oldest sponge steroids detected in sedimentary rocks underlie this cap carbonate, and so pre-date the end of the global Marinoan glaciations.

Urochordates have a sparse fossil record. A Precambrian fossil known as Yarnemia has been referred to the Urochordata, but this assignment is doubtful.

These fossils, which include: spicules; pinacocytes; porocytes; archeocytes; sclerocytes; and the internal cavity, have been classified as demosponges.
