Tyrannosaurus is one of the most well-known dinosaur species. The fossil found from the Hell Creek Formation in Montana, U.S. Teeth length is approximately 4.5 cm. Although the length is short, it is very thick, and it can be seen that if this tooth is complete, it will be very large. Although this fossilized tooth is damaged, the more valuable thing is that the serrations beside the teeth are still there. This tooth will be accompanied by the Tyrannosaurus model in the photo (restored from Jurassic Park). This model is very detailed and about 42*23*26 cm in length.
