Eurypterida (Sea Scorpions)
Length: 2.6 m (3.6 m if chelicerae (pincers) extended)
One of the largest arthropods of all time, she prefers to hunt in freshwater rather than the saltier homes of her ancestors.

Length: 2.07 m
While you could almost certainly train her to open doors, her relatively short legs mean that motorcycle rides probably aren't going to work too well. Her large eyes allow her to see well at night. Clever girl.

Length: 8 m
When she's not busy sleeping, Majungasaurus dined on sauropods such as Rapetosaurus and, occasionally, other Majungasaurus.
Tylosaurus pembinensis (Marsh, 1872)
Central / Western United States
Length: 15 m
More than a century after Cope and Marsh first dug up fossils of this giant squamate, our view of her has changed drastically. We now know that she possessed an asymmetrical tail fluke, was countershaded, lacked a dorsal crest, and is most likely more closely related to monitor lizards than she is to snakes.
Early - Late Cretaceous
Length: 10 - 13 m
One of the largest carnivores to ever walk the Earth, she has evolved serrated blade-like teeth, adapted to slicing through flesh with ease.

12 - 20 m
This ancient predatory whale's strange name comes from the fact that its bones were initially thought to belong to some sort of enormous non-avian sauropsid (reptile for those less cladistically inclined).

UPDATE: Shortly after I published this post, a new paper came out showing that Basilosaurus had the strongest bite force of any known mammal (over 3,600 pounds at its upper third premolar), enough to break open the skulls of juvenile Dorudon, another (smaller) ancient whale.
