Fossils of these and other types of invertebrates are frequently found in Kansas rocks. Although often overshadowed by the state's vertebrate fossils (such as sharks' teeth or the skeletons of huge swimming reptiles called mosasaurs), Kansas invertebrate fossils are nonetheless scientifically significant. Preparation with an air scribe is begun on the hard Devonian limestone revealing part of the pygidium and thorax. Other pieces of matrix are added to expose more of the trilobite. An essentially complete trilobite is revealed, though tips of pygidial and genal spines remain covered. More detailed prep work shows sweeping spines on the pygidium.These fossils, which were discovered in the Niobrara Chalk of western Kansas, lived during the later part of the Cretaceous Period, roughly 75 million years ago. Uintacrinus is a stemless crinoid, and specimens of these beautifully preserved crinoids from Kansas are on display in many of the major museums of the United States and Europe.The majority of fossils found in Arkansas are invertebrate fossils. Fossils can also consist of leaf imprints or fossil tree sections (such as trunks, roots or branches). In some rocks only the tracks, burrows and trails or traces of the animal were preserved. Plant fossils and trace fossils are included on the invertebrate fossil page.

The discipline of invertebrate paleontology evolved from the study of biology and geology in the late 18 th century. The early 19 th century saw collecting of invertebrate fossils from strata throughout Europe and Russia. In England, William Smith, a canal engineer working in the County Oxfordshire, worked out the occurances between fossils and ...Cenozoic marine Fossils Marine invertebrates. Paleogene sediments of the Coastal Plain have been studied since the early 1800s, longer than almost any other fossil-bearing sediments in the Americas.
