Squalodon is a prehistoric relative of river dolphins from the miocene epoch, however it was the size of an orca and had serrated teeth like a great white shark.
Where does it spawn?: Although that would seem pretty obvious, this is the same case with the microraptor, so they don’t spawn yet.
Then how do I get it?: Obtaining the spawn egg is the same as with microraptor, but the recipe is different and logically more expensive.
How do I tame a squalodon?: You can’t tame a squalodon, but it may be tamable in the future, luckily they aren’t aggressive unprovoked, but hurt them and they will eat you alive. They can even kill the wither in a pod (a group of dolphins/whales is called a pod).
