Fun facts
Teihivenator was named in 2017, making it one of the newest dinosaurs to get a scientific name.1
Its fossils were first discovered in the 1860s and were originally called 'Laelaps macropus'.1
Only a few leg bones and toe bones have been found, so scientists are still learning about this dinosaur.1
Teihivenator lived during the Maastrichtian age, about 72 to 66 million years ago.1
It belonged to a group called Tyrannosauroidea, which includes T. rex and its smaller cousins.1
The fossils were found in the Navesink Formation, which was once a shallow sea environment.1
