Dinosaurs with Rocks In Their Stomachs?

It's true (supposedly) Certain dinosaurs would swallow rocks into their stomachs, as the bulk of their diet was coarse and fibrous, the rocks in  the stomach made like a natural pulverizer to grind up the food and make it easier to digest.  Want made it curios to me, is how in the HELL did they figure that out, and more importantly How did they communicate something like that to the other Dinosaurs?  I mean if your the first to figure it out, how do you pass such info on?  What it's like "Hey!  Myron, check this out, in the morning for breakfast before you start munching on that elm, try swallowing some of these rocks.  Gives ya an excellent BM!"  Visualize a Bronto rolling his eyes.
Yep these are the things that come to mind when I'm doing routine re-pairs!  And that was today ALOT of re-pairs!  Thank you so much for your trust!  And Thanks to the couple from Norway who put a deposit down on a special ordered, re-paint on that old Jamis cruiser we rescued from the ditch the other day!  He needed something tall, as he's...something tall!  And a Special thanks for the great compliments on our little enterprise here!  Seems they winter here and last year they took home pics of the clown bike and put it on their home page, apparently they've had ALOT of people download the pic!  Seems there's alot of them floating around over there.  Not a day passes that at least one person takes a pic of it!  Makes a Daddy so proud!  And the nice couple from...somewhere up North, came in and picked out the ladies Road master and the Schwinn I just bought yesterday, for a re-furb!  And thank YOU for all the wonderful compliments as well.  Speaking of stuff bought, the Murray Beach Cruiser I bought with the Schwinn yesterday sold as soon as I opened the doors this morning...And I hadn't even worked on it yet!  He liked it just the way it was.  Thanks to you sir!
Picked up a real sweet ladies Univega hybrid today, needs some work but will hopefully be out by tomorrow or Tuesday.  Sorry i have no new builds to share, 'twas Angela, Kaleb and I today, Angi manned the front and Kaleb did tear down parts bikes, but I had the re-furb and several re-pairs to finish...But TOMORROW...Look out!
Y'all have a restful night!


Sauropods and stegosaurus do not chew the plants they eat. They simply shred the leaves and stems and swallow the shreds whole-rocks within their stomachs then batter the swallowed plant material to a pulp. A good strategy with cycads, which have soft, pulpy interiors, this approach doesn't work well with angiosperms, which are much woodier and tougher. With the rise of angiosperm plants at the beginning of the Cretaceous, sauropods and stegosaurus were replaced by iguanodonts, which had "chewing" teeth (figure 45.51). The jaws of iguanodonts contain enormous batteries of grinding teeth that shred, pound, and grind even the toughest angiosperms. Even bigger than stegosaurus, Iguanodon was as heavy as an elephant.
