National Lampoon's The Tail of Paulus

This right here is a screenplay for an upcoming film developed by Gibson Settlement Animation (the same company that brought forth the needs-to-be completed Xanadu script), and it is about six or so prehistoric animals from a huge array of eras (Paleozoic thru Cenozoic) meeting up with the Neanderthal ancestors of the Griswolds, as they all try to migrate west from an impending ice age, and a ravenous Sphenacodon, called "Mud-butt." Jenna Ortega will be in it, as will Kevin James, and Kimberly Brooks as Paulus, a baby stegosaurus.
It will be animated by Illumination, as the first to be done so State-side since Hop (2011), and distributed by Warner Bros. in the US and Universal City Studios internationally thru DreamWorks Animation. 
== Plot ==
In 2015 San Francisco, before the events of Vacation, Clark Griswold and his wife Ellen are dredging their backyard, when they come across a fossil of a strange reptile. While wondering what it could be, they encounter an anthropomorphic raven named Alex, who then transforms into a prehistoric ancestor, Alexornis. Alex tells them of a story set in the "quasi-Late Cretaceous" period, 66.5 million years ago, about his best friend Paulus, and their own ancestors. 
The film, now in animation, shows a mommy Stegosaurus tending to a bunch of her hatch-lings, but one egg didn't hatch. This almost became a meal to a hungry Troodon, who made off with the egg until he slams into a chalicothere. The egg then rolls down the hill, thru several tunnels, into the trunk of two mammoths, Big Mammoth (Brad Garrett) and Little Mammoth (Bill Hader, but sped-up), and several of their traveling companions, including Melissa (Jenna Ortega), a Procynosuchus who dreams of being able to fly; Harry (John Leguizamo), a Hapalops sloth who is a scaredy-cat; Helen (Kari Wahlgren), a Kvabebihyrax (hippo-eyed hyrax) who is a narcissistic one; Alex, the aforementioned dino-bird; and Erin (Sharon Stone, and if she's not available, then Holly Hunter), a terror bird. They all raise the hatch-ling, who they name Paulus, as their own. 
Three years later, the animals in the Ice Valley brace for the forthcoming ice age, evident with a coincidental famine. A mastodon (Kevin James) is on the run from a pursuing lizard-like creature (Ben Burtt/Frank Welker), but manages to trap the creature in a ice enclosure made from the falling ice from the entrance to the valley. He then tries to reach for a berry, only to be stopped by Big Mammoth...
