These sauropod fossils are, unfortunately, rare. For every sauropod tooth found, about 30 predatory dinosaur (theropod) teeth are found. It’s not clear why there was such an imbalance between the carnivores and the herbivores.
What are often mistaken for dinosaur teeth?
Which Are the Dinosaur Teeth? … The rugose corals (also known as solitary or horn corals) are very often mistaken for dinosaur teeth but are older than the oldest dinosaurs, having gone extinct around 250 million years ago (the oldest known dinosaurs are around 230 million years old).
Are dinosaur fossils rare?
Very few things do. A specific set of circumstances and conditions are needed for fossilisation to occur, so it is actually a very rare event. Most things that die rot away completely, leaving nothing behind. Nearly all fossils we find – around 99% – are from marine animals such as shellfish and sharks.
Where are dinosaur teeth found?
The tiniest teeth likely belong to the needle-like teeth of the paravian dinosaurs like Microraptor.
