This is the profile of a completely articulated saber-toothed cat. It's skull actually looks rather small for the rest of its body. I suppose it makes up for this with the size of its canines.

This little frog communicates by waving its arm at other frog. It is now extinct in the wild, last seen in 2007 shortly after David Attenborough filmed a segment featuring the frogs for "Life In Cold Blood"

Great looking bird getting ready for a splash.
The white-tailed eagle is the largest UK bird of prey. It has brown body plumage with a conspicuously pale head and neck which can be almost white in older birds, and the tail feathers of adults are white. It went extinct in the UK during the early 20th century, due to illegal killing, and the present population has been reintroduced.
A rare breeding bird which was previously confined to the west coast of Scotland, though a reintroduction programme is taking place in east Scotland.
I've personally seen them in the wild on the Isle of Mull and Skye
