One of the biggest teeth in the world from a new type of dinosaur could rewrite the history of prehistoric evolution.
A team of European researchers recovered fossils from a geological formation in the Swiss Alps that dates back to the Late Triassic.
The tooth is four inches long and has a root twice as wide as any other known reptile. Scientists think the ancient giant was roughly half the size of a blue whale.
The researchers were shocked to find a giant dinosaur tooth.
It's a major embarrassment for paleontology that we don't know so much about these.
According to the study, the upper limits of the size of the tooth of late-Triassic ichthyosaurs, like this one who lived about 200 million years ago, may be represented by the tooth.
There are many questions.
It's hard to say if the tooth is from a large ichthyosaur with giant teeth or an average-sized tooth.
The current rate of climate change and carbon emissions may allow him to get his wish.
Scientists say that humans have caused the worst ocean extinction event since asteroids killed dinosaurs.
