Bryozoans are small animals (just large enough to be seen with the naked eye) that live exclusively in colonies. In fact, the Phylum Bryozoa is the only animal phylum in which all known species form colonies. The name comes from two Greek words, bryon (moss) and zoon (animal ...Invertebrate Definition. Invertebrates are animals that don’t have a backbone. The vertebral column is another name for the backbone. Over 90% of all species on Earth are invertebrates, and invertebrate …

The extinct invertebrate Arthropleura, a relative of centipedes and millipedes, lived during the Carboniferous Period (359.2 million to 299 million years ago) and ranks among the largest insects ever described; estimates from fossil armour segments suggest that the species could have grown to more than 2 metres (6.6….

The Cambrian fauna is responsible for the incredible increase in diversity seen in the fossil record, known as the Cambrian explosion. Some major taxa included in the Cambrian fauna are trilobites, inarticulate brachiopods, and early representatives of echinoderms. Trilobites are a superphylum (Trilobitomorpha) of arthropods that are a hallmark ...Cambrian Period - Fossils, Paleoclimate, Evolution: Global climate during Cambrian time was probably warmer and more equable than today. An absence of either land or landlocked seas at the Cambrian poles may have prevented the accumulation of polar ice caps. The general absence of glacial till deposits of Cambrian age is more notable, because these deposits are common and widespread in upper ...
The harsh Permian climate did not support a rich diversity of life, but rare fossils of lungfish, sharks, and fish have been found. The Mesozoic:The Mesozoic is represented in Kansas primarily by Cretaceous rocks. Fossils of plants and marine invertebrates provide evidence that a shallow, warm sea covered the western part of the state at this time.The largest source of empirical data on the history of life largely derives from the marine invertebrates. Their rich fossil record is an important testing ground for macroecological and macroevolutionary theory, but much of this historical biodiversity remains locked away in consolidated sediments. Manually preparing invertebrate fossils out of their matrix can require weeks to months of ...The collection ranks among the top 10 largest fossil invertebrate collections in the country with over 900,000 fossil invertebrate and microfossil specimens from around the world. The KU Invertebrate Paleontology collection has been used in research for over 125 years and contains more than 11,000 type specimens.Among a shipment of early Ordovician invertebrate fossils that Beckwith donated to the US National Museum (part of the Smithsonian Institution in Washington D.C.), a selection of brachiopods became the first paleontologic specimens from Fossil Mountain ever formally described in the scientific literature (1936 and 1938); mysteriously, though ...
Crinoids are echinoderms and are true animals even though they are commonly called sea lilies. The body lies in a cup-shaped skeleton (calyx) made out of interlocking calcium carbonate plates. Arms attached to the calyx also have a plated skeleton and are used to capture food particles. In most species, the calyx is anchored to the sea floor by ...Bryozoan fossils occur in many forms, including finger-shaped, fan-shaped, mats, spiralling fans, and massive irregular mounds. Many of the fossils, if examined closely with a magnifying glass, will show the individual pits where the individual bryozoans lived. ...

In Ohio, trilobite fossils are known from rocks of Cambrian (not exposed at the surface in Ohio), Ordovician, Silurian, Devonian, Mississippian, and Pennsylvanian ages. In 1985, the Ordovician trilobite genus Isotelus, which occurs in southwestern Ohio, was named the official state invertebrate fossil.
