GEN 1:29 (Pre-Flood)Then God said, “I give you every seed-bearing plant on the face of the whole earth and every tree that has fruit with seed in it. They will be yours for food. And to all the beasts of the earth and all the birds in the sky and all the creatures that move along the ground—everything that has the breath of life in it—I give every green plant for food.” And it was so.

Genesis 9 (Post Flood)
Then God blessed Noah and his sons, saying to them, “Be fruitful and increase in number and fill the earth. The fear and dread of you will fall on all the beasts of the earth, and on all the birds in the sky, on every creature that moves along the ground, and on all the fish in the sea; they are given into your hands. Everything that lives and moves about will be food for you. Just as I gave you the green plants, I now give you everything.

Here is another one of those “just so” stories that vex even the minds of some evolutionists. In this article, scientists discover that many of the fearsome “meat-eating” dinosaurs had a diet consisting mainly of vegetation. The surprising findings came from the study of such items as fossilized stomach contents and dinosaur droppings.

After the research findings were known, science needed an explanation that fit in with other preconcieved Darwinian stories (like dinosaurs to birds) so the notion is advanced that dinosaurs evolved on purpose as it were into birds because of the sudden lack of meat in their environments. This is dumb for many reasons but chief among them is te idea that birds are vegetarians. Birds are certainly at the least omnivores and some are most decidedly carnivorous,

It’s interesting isn’t it that both Genesis and now science believe that meat-eating dinosaurs were at one time; plant eaters. Genesis and science simply disagree on which came first……s8int.com


The Most Terrifying Meat-eating Dinosaurs Suddenly Went Vegetarian

The theropod dinosaurs, like Tyrannosaurus rex and Velociraptor, were some of the most fearsome carnivores ever. Yet most of these perfect hunters abandoned live prey in favor of a more peaceful, vegetarian existence…which started their evolution into birds.

Researchers recently set out to determine the diet of 90 different theropod species. They were expecting to find a lot of meat-eating – after all, theropods are known informally as the predatory dinosaurs. But even confirming that hypothesis would be tricky because so little evidence of dinosaur diet remains.

Teeth do often pass into the fossil record, but it’s not always easy to figure out diet based on just teeth. While the sharp teeth and jaw of a T. rex is obviously that of a fearsome superpredator and the blunt teeth of a Triceratops obviously belong to a plant eater, a lot of dinosaur teeth fall somewhere in the middle. A lot of therapod dinosaurs have strange, peg-like teeth which seem less than ideal for either a carnivorous or herbivorous existence, so figuring out what they ate becomes a real challenge.

The good news is that there are lots of other types of evidence: fossilized poop, preserved stomach contents, marks on the teeth, and even stones inside the stomach that would have been used to digest vegetation all provide clues to dinosaur diet. The researchers used statistical analysis to figure out which of these bits of evidence were most strongly correlated with eating meat or eating plants, and then look for other dinosaurs that also possessed those features.

The results were shocking. Many of the supposedly carnivorous therapod dinosaurs were actually eating plants. The highly carnivorous diets of T. rex and the Velociraptor actually made them the unusual ones among their dinosaur peers. Researcher Lindsay Zanno explains in words that will surely come back to haunt her if ever a Jurassic Park scenario breaks out:

“Most theropods are clearly adapted to a predatory lifestyle, but somewhere on the line to birds, predatory dinosaurs went soft.

Indeed, a lot of the adaptations these dinosaurs underwent as they ate more and more plants brought them closer to modern birds. Along multiple evolutionary lines, once carnivorous dinosaurs lost their flesh-ripping teeth in favor of weird new teeth in the shapes of pegs, wedges, or even leaves. They then lost their teeth completely, as they evolved a bird-like beak. Zanno explains:

“This is a clear-cut indication that the repeated evolution of a toothless beak in theropod dinosaurs is linked to plant eating. Once a beak appeared on the scene, it continued to evolve. Theropods would have used their beaks in a myriad of ways; they still do.”

So why did the perfect hunters of the dinosaur world switch to vegetarianism? It might have been caused by the breakup of continents, which opened up new and unusual habitats for these dinosaurs to explore. However it happened, the theropods – particularly the coelurosaur subgroup, which included T. rex and Velociraptor – became one of the most diverse and successful dinosaur groups of the Cretaceous Period. Maybe it really is worth eating your vegetables after all.
