The global fossil record, as currently documented, is not truly global (4, 15-17), and there is substantial variation through geological time in the numbers, sizes, and locations of spatial regions from which fossils have been reported. Therefore, nominally global diversity estimates among intervals of geological time derive from different ...Most paleontologists work at universities and museums. Some may work for federal or state governments, or in private industry. University paleontologists mostly teach and do research. Invertebrate paleontologists are usually in geology departments. Vertebrate paleontologists and paleobotanists are more often members of biology departments.Insects belonging to the genus Lemmatophora are relatively common fossils at the Elmo site.

For example, large communities of 200-million-year-old invertebrate marine fossils found in the deserts of Nevada, in the United States, tell us that certain areas of the state were covered by water during that period of time./ Invertebrate Fossils / Bivalves. Bivalves are molluscs with bodies that are enclosed in a shell of two halves (valves) that can be opened at one end. The animal pumps water in and out of the shell. This water brings dissolved oxygen for the animal to breathe with gills and, in most species, food particles. Bivalves can be found in fresh water ...Their fossils are common in the Pennsylvanian and Permian limestones of eastern Kansas.
