About #279: Very interesting account ! (as usual...). But, it's hard to believe the presence of the arctodus simus would provoke the scarcity of the other predators. Especially by taking into account the existence of so numerous great species of big herbivores: American buffalos (which should live in big herds like the extant American buffalos before the white men (coming from Europa) invasion , elephants, elks, deers and so on... The arctodus simus could it be a so efficient predator ? Or a so efficient scavenger always running through its environment in order to detect any corpse and to frighten any predators around ? Or rather: Either was the arctodus simus a very abundant predator, or were the herbivores very scarce too, because of the very harsh life ? But I don't want to believe that the arctodus simus would have been such a nightmarish beast. The other predators could not be without resources against it, I just imagine several atrox lions, or 2 or 3 dozens of dire wolwes protecting their kills... Perhaps did the arctodus simus enjoy a superior metabolism ? I joke... I just want to tell that opposed to a very powerful predator the other predators adapt themselves. The only one predator having made the other predators scarce is the human specy. We know why... But here, we are speaking about predator mammals. I would rather believe that the fossilization conditions weren' t good at all (non-conservative ground or environment). Perhaps too, the confirmed presence of huge predators would have made very careful the first humans of these lands. |
