Seemingly part sloth and part…horse? okapi? who knows…chalicotheriums are herbivorous megafauna common in Lost Word forests. Like most herbivores, they’re content to leave you alone, but are surprisingly dangerous if you get between one and its young. Meanwhile the kaprosuchus is a crocodilian-like creature. Don’t look for them in the water though; they lunge through the woods instead, which may explain their ramming attack.
While making a courier run, adventures’ gliders crash-land in the Shivering Forest. They soon find out how the woods got that name: from the way the undergrowth quivers as hungry kaprosuchuses lunge for their prey.
In their last adventure, a party of sellswords shut off an artifact that had been powering a mini ice age. As the glacial sheets retreat, a new land bridge is revealed connecting Falconyr to distant Ikari. Among the first creatures to take advantage of the bridge are the great chalicotheriums, knuckling their way toward the new grazing lands they scent on the winds.
Adventurers receive reports of drake attacks in the nearby woods. It turns out the attacks are really being caused by primitive crocodile-like creatures—kaprosuchuses, the local sage says. Weirdly though, these great lizards disappear upon being slain. A sorcerer has discovered a way to use ancient cave paintings to summon prehistoric animals.

Note that Pathfinder Adventure Path #91: Battle of Bloodmarch Hill has animal companion statistics for chalicotheriums.
Speaking of primitive crocodilians, a little while ago askserithal wrote:
I'm trying to make statistics for this prehistoric croc and I can't really think of any good bases for it because it has so many things it's like. Any suggestions?
I would try the dwarf caiman from Pathfinder Adventure Path #55: The Wormwood Mutiny. Maybe advance it to 1 or 2 HD and give it some kind of speed surge (like drakes have) or similar special ability to reflect its quickness.
Did you guys hear about my research project? I’m investigating what makes tortoiseshell cats so adorable. That’s right, I’m trying to prove…the Calico Theorem.
In other news I’m traveling at the moment but will try to update as best I can.
