... into small and large cat guilds greatly improves the stability of the models. Significant insights emerge for three long-canine cats: Smilodon populator , Paramachairodus orientalis , and Dinofelis sp. from Olduvai Gorge (East Africa). S. populator and P. orientalis are both predicted to have been closed...

..., had tooth crown growth rates similar to modern lions. This contrasts with the longer and thinner, dirk-toothed saber species in the genus Smilodon , S. gracilis and S. fatalis , which had much faster growth rates. With a more rapid growth rate, Smilodon reduced the total duration of crown growth...

..., biologists have toyed on and off with the possibility of large mutations – the emergence of ‘hopeful monsters’ – but they have rarely been convinced. Only a minority of mutations, even small ones, will be beneficial. Sometimes small populations of animals or plants will become isolated, a higher than normal...

.... dirus in southern Nevada toward the end of the Pleistocene, between 14.59 and 14.27 ka. This is the first confirmed record of dire wolf in the upper Las Vegas Wash, and the first in the entire Pleistocene fossil record of Nevada. In 2003, fossils of Smilodon fatalis were discovered in the upper Las...

.... Through stable isotopes of carbon and a Bayesian mixing model, we analyze time-successive (nearly contemporaneous), late Miocene carnivoran populations from two fossil sites (Batallones-1 and Batallones-3) from central Spain. Stable isotopes of carbon in tooth enamel provide a reliable and direct...

Thus, middle-Late Pleistocene ecosystems were potentially controlled from the bottom up rather than from the top down...

Scavenging megaherbivore carcasses was probably another frequent way of feeding for A. angustidens ( Soibelzon, 2002a ); a similar strategy has been invoked for Arctodus simus (see...
