Morning ProDeo. Good question. Yes they would have had those sharp teeth ( in my opinion ). Somewhere in the original Dino thread part one are some skulls of animals with very sharp and ugly teeth but the actually only eat fruit or grass.
What did a t-Rex eat in the garden ? We don’t know, perhaps he was a melon eater. ?
What did this guy eat?
>>>>Diet. Green Iguanas are primarily herbivores, with captives feeding on leaves such as turnip greens, mustard greens, dandelion greens, flowers, fruit, and growing shoots of upwards of 100 different species of plant. In Panama one of the green iguana’s favourite foods is wild plum, Spondias mombin.
The food should be chopped up to make eating it easier. Some greens you could feed your pet include collard, mustard & dandelion greens, turnip greens, kale, and romaine lettuce. Vegetables your iguana may like are shredded carrots, peas, green beans & other beans, bell peppers, and squash.<<<<
If everything was bigger in the old world there was perhaps giant fruit and plants as well. Perfect for a giant T-Rex.
I heard a palaeontologist on the radio this summer talking about that he thinks t-trex had lips, like the iguana. So those sharp teeth would not be as prominent as Hollywood would lead us believe. In short we don’t know what they ate, we can guess . Genesis would imply greenery. They may have originally ate green herb as Genesis says they switched to carrion after the curse.
Are you aware of the lion who refused to eat meat? Lived 9 years on vegetables.
