1

Mikadocephalus is known from a skull that was so crushed and jumbled that it looked like a game of pick-up sticks, which is how it got its name.1

2

It lived about 247 to 237 million years ago, during the Middle Triassic, making it one of the earliest big ichthyosaurs.4

3

Its fossils were found in the Besano Formation, which was once a warm, shallow lagoon with poor oxygen at the bottom.1

4

Scientists think Mikadocephalus might actually be the same animal as another ichthyosaur called Besanosaurus, because they look very similar.1

5

The species name gracilirostris means 'slender snout', because its jaws were long and thin.1

Scientists still debate whether Mikadocephalus is its own species or the same as Besanosaurus, since the skull is so crushed.1
