PaleoHaiku #9: Top-Heavy Cervid

Irish elk, large deer
Pleistocene ungulate with
An impressive rack.

PaleoLimerick #10: Prodigious 'Possum

Diprotodon was a marsupial that
Weighed 700 times that of a cat
If they ever met
I would certainly have bet
That the cat would have become very flat.

Genyornis was an oversized duck
That waded through Pleistocene muck
Its gigantic feet
Contained little meat
But her rump was worth more than a buck
