A ten-foot-long, 600 pound synapsid of the genus Edaphosaurus forages in a brackish mangrove-like swamp of gymnosperms of the genus Cordaites 300 million years ago in what is today Western Europe.  . Like its better-known synapsid cousin Dimetrodon, Edaphosaurus had a large sail on its back supported by elongated neural spines, however unlike Dimetrodon, these spines include numerous short cross bars; while the sail may have served the purpose of both helping to regulate body temperature and as sexual display, the purpose of the cross bars is unknown. Jaw and teeth structure suggests that Edaphosaurus probably dined on both plants and small invertebrates, such as mollusks.  . Tree-like Cordaites, now extinct, grew on wet ground similar to the Everglades in Florida, numerous fossils of which are now found associated with coal deposits. Also in this image are several examples of extinct seed fern of the genus Neuropteris as well as smaller examples of generic fern that may have been present during the period.  . Other fauna include two examples of the large dragonfly-like Meganeura, a centipede, and in the foreground a juvenile prehistoric shark of the genus Xenacanthus, its distinctive spine projecting from the back of its head and out of the water.A ten-foot-long, 600 pound synapsid of the genus Edaphosaurus forages in a brackish mangrove-like swamp of gymnosperms of the genus Cordaites 300 million years ago in what is today Western Europe.  .

A pack of dire wolves crosses paths with two mammoths 150 thousand years ago during the Upper (Tarantian) Pleistocene Epoch in North America. A late fall dusting of snow heralds the coming winter. This was a period of glaciation known in North America as the Illinoian Stage when the Laurentide ice sheet covered much of the continent to a depth of 2 miles. . . The extinct Dire Wolf was closely related to the modern Gray Wolf, though is not the direct ancestor of known wolf today. The Dire Wolf was larger and stockier than the Gray Wolf with proportionally shorter legs. Mammoths were close relatives of modern elephants and approximately the same size, though Asian mammoths were somewhat larger than their American cousins. Mammoths had massive tusks. Both mammoths and dire wolves disappeared from the North American continent about ten thousand years ago.A pack of dire wolves crosses paths with two mammoths 150 thousand years ago during the Upper (Tarantian) Pleistocene Epoch in North America.
