Procoptodon Maddocki
''Procoptodon'' is an extinct genus of giant short-faced (sthenurine) kangaroos that lived in Australia during the Pleistocene Epoch. ''P. goliah'', the largest known kangaroo species that ever existed, stood at about . They weighed about . Other members of the genus were smaller, however; ''Procoptodon gilli'' was the smallest of all of the sthenurine kangaroos, standing approximately tall. The genus is derived from ''Simosthenurus'', making the latter genus paraphyletic. Description ''Procoptodon'' physiology was likely similar to that of the contemporary kangaroos; however, ''Procoptodon goliah'' was characterised by its large size. These sthenurines, or short-faced kangaroos, included species that were more than three times the size of the largest kangaroos living today. The largest, ''P. goliah'', was tall and weighed up to . These animals lived alongside modern species of kangaroos, but specialised on a diet of leaves from trees and shrubs. ''Procoptodon'' were large and ...

Richard Owen
Sir Richard Owen (20 July 1804 – 18 December 1892) was an English biologist, comparative anatomy, comparative anatomist and paleontology, palaeontologist. Owen is generally considered to have been an outstanding naturalist with a remarkable gift for interpreting fossils. Owen produced a vast array of scientific work, but is probably best remembered today for coining the word ''Dinosauria'' (meaning "Terrible Reptile" or "Fearfully Great Reptile"). An outspoken critic of Charles Darwin's theory of evolution by natural selection, Owen agreed with Darwin that evolution occurred but thought it was more complex than outlined in Darwin's ''On the Origin of Species''.[''Wikipedia:Citing sources, page range too broad''] Owen's approach to evolution can be considered to have anticipated the issues that have gained greater attention with the recent emergence of evolutionary developmental biology. Owen was the first president of the Microscopical Society of London in 1839 and edited ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
