Large Pleistocene Carnivores Kept Megaherbivore Populations in Check

GeorgiaBeforePeople

A brand new study suggests large packs of big carnivores kept populations of megaherbivores in check during the Pleistocene.  This finding seems like a no-brainer, but some paleoecologists believe megaherbivores suffered little mortality attributable to predation and were instead limited by the availability of plant resources.  The results of this study imply that large carnivore predation of megaherbivores was beneficial for the environment as a whole.  Lowering the overall population of megaherbivores prevented the landscape from being denuded and protected vegetated habitats for birds and other small animals.

The authors of this study compared tooth size and shoulder height between large Pleistocene carnivores and modern carnivores.  They determined that Pleistocene carnivores were on average 50%-100% larger than modern day carnivores.  This greater size gave them the ability to better prey on megaherbivores.  Even though these carnivores were larger, they likely needed to hunt in packs to take down such megaherbivores as…
