Transition fossils- Part 1... Tetrapodophis... Greek for "four-footed snake"
Transition fossil are usually quite rare and have been elusive to find. 
-
This is changing.

It doesn't take a rocket scientist to deduce that snakes evolved from lizards but the exact transition has proved very elusive.

We have some living species today who are clearly in a state of transition but are still decidedly lizard or snake.

Tetrapodophis is clearly what we have been looking for, for the original transition from lizard to snake. 
-
The geological timing is right (matches molecular data of when the split should have occurred) and the fossils from Brazil are excellent.

In this instance we clearly have a snake with four limbs as opposed to a legless lizard or a snake with vestigial hind limbs in the form of spurs.

Pics by University of Portsmouth’s David Martill and colleagues.

The fossil had been in a private collection for many decades before its full importance was realized.
