Carnivorous ground sloths
The revelation that ground sloths were actually rapacious predators
had led to a worldwide re-examination of fossil evidence. Some of
the new discoveries that are turning paleontology upside down:
Allosaurus, lacking a monster oleocranon, was forced to use its
foreclaws to pull down treelimbs so it could nibble the leaves.
Stegosaurs used those tail spikes to impale small theropods, which
they then consumed at their leisure.
Mammals remained small throughout the Mesozoic thanks to
insectivorous sauropods, which used their long necks to ferret out
(no pun intended) the hairy little treats.
Ceratopsian beaks closely resemble the beak of the Common Snapping
Turtle, _Chelydra serpentina_, and were clearly used for tearing
The cheek tooth batteries of hadrosaurs were obviously used to grind
up animal bones, making them true osteovores. Pachycephalosaur
skulls are thought to have been their preferred food.
Pterosaurs are thought to have hunted the triconodont bats to
extinction, thus accounting for the lack of fossil evidence of the
Ankylosaurs used their armored tails to pound tyrannosaurs into a
thin pulpy substance, which they could then consume with their rather
A spectacular find in the South Dakota badlands indicates that, at
least for a short time during the Miocene, pigs really did fly.
I bet ole George (Cuvier, that is) must be rolling in his grave.
All in fun,
