Paleontologists are hypothesizing that rounded, fist sized rocks that came from what is now Wisconsin, may have been carried all the way to modern day Wyoming, in the bellies of gigantic Jurassic sauropods like Diplodocrus millions of years ago. The stones would have been swallowed to help them digest plants like some birds and reptiles still do today. The distance between where the stones were ingested and where they were found is about a thousand miles, and some paleo-skeptics question how the creatures travelled all that way. Professor Joshua Malone, who wrote up his hypothesis for the journal Terra Nova, points out that they may have hit the road in pairs, reminding his peers that cars were much larger then. www.livescience.com/jurassic-dinosaurs-migrated.html |

James Michener's excellent "Centennial" opens with a diplodocus mostly submerged in a lake, searching the shoreline for just the right rock to swallow to help her digest plant matter.
One of my all-time favorite books.

This is what the Mrs. and I like reading and watching. Paleontology is facinating!

Maybe dinosaurs had gizzards. That's pretty neat.

Time and space, boggle the mind. Dinosaurs ruled for about 175 million years, they're a gas. I mean fossil fuel.

I hypothesize that some of the rocks were accidentily swallowed only to be ejected later in an enormous build up of highly pressurized gas that ejected said rocks several hundereds of miles. The escaping gas built up over a millinium until the normally docile creatures could stand it no lomger and enmass commited suicide by leaping to their deaths off of cliffs.

Were two of these cliff leaping dinos named Thelma and Louise? |
