Iguanasaurus is the earliest dinosaur discovered in the world. First excavated in Britain, Iguanasaurus is an animal that is neither a mammal nor a reptile. Since the word "dinosaur" did not exist at that time, it was also the direct cause of the word "dinosaur". Subsequently, its fossils were discovered one after another around the world, so its research gradually reached a new level. Because its teeth resembled those of an iguana, people gave it the name Iguanasaurus. This dragon's staple food is plants. Because the characteristics of its teeth are different from those of other animals, people have long inferred that it was a herbivorous dinosaur.
As long as you look at its skull, you can see that there are no teeth in the front of its mouth, but there is a dense row of teeth in the back of its mouth, and these tooth surfaces covered with jagged packets have been There is a lot of wear and tear, which is enough to show that Iguanasaurus put the hard plant in its mouth and chewed it repeatedly before swallowing it.
So what kind of plants did the iguana dragon eat? To solve this mystery, we must first find clues from the dense plants that existed during their habitat. Near the site where the Iguanasaurus fossils were excavated, people also found fossilized leaves of coniferous trees such as horsetails, ferns, and pines, as well as fossilized seeds similar to pine cones.
The iguanasaurus is 10 meters long and can reach 5 meters when standing upright. The iguanasaurus that could walk on its hind limbs probably stood upright and used its forelimbs to pull the lower branches of the coniferous trees in front of itself, then bit it off the tree, and finally slowly ate its leaves and seeds. . Of course, when eating horsetails near water or in humid areas, they land on their forelimbs and hang their entire body low to feed.
