In this lab you will look at bryozoans and corals from Indiana and learn the basics of their classification and anatomy.Each animal was attached to the inside of its pit and could not leave the pit. Bryozoa feed on microscopic organisms floating in the water, which they grab with tiny tentacles. Bryozoan fossils can be found in Kentucky's Ordovician, Silurian, Devonian, Mississippian, and Pennsylvanian rocks.moss animal, also called bryozoan, any member of the phylum Bryozoa (also called Polyzoa or Ectoprocta), in which there are about 5,000 extant species.

The discovery of giant stromatolite fossils in the Navajo Sandstone is part of a growing body of research challenging some long-held …Geological ages of fossils are never as old as the origin of a group due to vagaries of sampling, but a time-calibrated tree can reveal evolutionary events absent from the fossil record. For example, until last year ( 8 ), bryozoan fossils were unknown from the Cambrian period (539 to 485 million years ago), when all other durably skeletonized ...Crinoids are marine animals belonging to the phylum Echinodermata and the class Crinoidea.

In most cases you may not be able to identify your fossil more specifically than as a bryozoan. Bryozoans were able to live almost anywhere: on a brachiopod shell, the side of a cephalopod, coating sea plants, or in an individual colony on the sea floor. The animal must exert muscle power to open the shells, and when their muscles are relaxed the shells close. As a result, fossil brachiopods are frequently found with both sides together. This is different from the bivalves introduced in the next section. Brachiopod shells vary greatly in shape and texture. They are typically 2 to 4 cm in size ... Places to view and collect Ohio Fossils.

Fossils are the traces or remains of organisms buried and preserved in sediments. They consist not only of hard body parts, such as bone and shell, but also may be impressions of plants, or tracks, trails, and burrows. Fossils can tell us what life was like on Earth in ancient geologic time, helping geologists describe ancient depositional environments and …Sponges (Phylum Porifera) are the simplest major group of animals; their earliest fossils appear in the late Precambrian.
