Myophoria, genus of extinct clams found as fossils in Triassic rocks. It is readily identified by its distinctive shell form and ornamentation, and thus it is a useful guide, or index, fossil for the Triassic Period (251 million to 200 million years ago). The shell in Myophoria is angular, with Eospirifer, genus of extinct brachiopods, or lamp shells, found as fossils in Middle Silurian to Lower Devonian marine rocks (the Silurian Period ended and the following Devonian Period began about 416 million years ago). The genus Eospirifer is closely related to other genera included in the brachiopod group known as the spiriferids, a formerly important group of animals. Irish elk Irish elk, (Megaloceros giganteus), extinct species of deer, characterized by immense body size and wide antlers, commonly found as fossils in Pleistocene deposits in Europe and Asia (the Pleistocene Epoch began 2.6 million years ago and ended about 11,700 years ago). Despite its distribution Also called faunal dating, it dates fossils relatives to one another using "index" fossils that work as markers. (e.g. Irish elk died out in 10,600 yBP so fossils must be dated before then, e.g. changes in pig molars = specific molar shape/size shows which site is older/younger For example, giant deer—sometimes called Irish elk—provide useful information based on their extinction (Figure 8.15). That is, because the species appears to have died out in northern Europe around 10,600 yBP, the presence of Irish elk fossils in a northern European site indicates that the site predates 10,600 yBP.

What makes a good index fossil and why is it different from other fossils? It is distinctive, widespread, abundant and limited in geologic time. They were only alive for a short amount of time. What do ice cores tell scientist about the past? What the temperature was like on the planet 800,000 years ago. It has also helped prove current warming In body size, the Irish Elk matched the extant moose subspecies of Alaska (Alces alces gigas) as the largest known deer. The Irish Elk is estimated to have attained a total mass of 540–600 kg (1,190–1,320 lb), with large specimens having weighed 700 kg (1,500 lb) or more, roughly similar to the Alaskan Moose. Molyneux erroneously identified the Irish elk with the American moose, while others thought the Irish elk was identical with the European reindeer. Not until 1812 did the great French scientist Georges Cuvier document that the Irish elk, along with other fossil vertebrates such as the mammoth, Irish elk, (Megaloceros giganteus), also called Irish deer or giant deer, extinct species of deer, characterized by immense body size and wide antlers, commonly found as fossils in Pleistocene deposits in Europe and Asia (the Pleistocene Epoch began 2.6 million years ago and ended about 11,700 years ago). Index Fossil. Remains of species that existed on Earth for a relatively short period of time, were abundant and widespread geographically, and can be used by geologists to assign the ages of rock layers.
Everything you should know about the Irish Elk. The Irish Elk is the largest deer species to ever walk the earth Home; Animal Index Though no one alive today has ever seen one in the flesh, the fossilized To carry such heavy antlers, it is likely they were incredibly muscular, particularly in their necks, chests, and backs

Irish Elk The Irish Elk, belonging to family Cervidae, is an extinct mammal. In contrary to its name, the Irish Elk was neither an Elk (belonging to the same group as North American Elk or the European Elk, which is popularly known as Moose in Northern America) nor it was exclusively found in or around Ireland.

The Irish elk (Megaloceros giganteus) also called the giant deer or Irish giant deer, is an extinct species of deer in the genus Megaloceros and is one of the largest deer that ever lived.
