So what we have here is an animation of the fossil shrimp Cascolus ravitis
and this animation was put together through a lot of detailed work by the team,
in particular Derek Siveter and Carolyn Lewis of Oxford University,
Mark Sutton at Imperial College London, Derek Briggs at Yale University
and David Legg latterly of Oxford University and myself.
The different parts of the animal are picked out in different colours
and the first thing to note is that it's so beautifully preserved in three dimensions.
There is no compaction whatsoever and these very long green thread-like structures
along the whole length of the animal are micron wide threads coming from the first limb.
We've coloured the eyes in red and you can see them here beautifully preserved at the front of the animal
and they're large and preserved on stalks and they actually had all round vision.
So they could see in front of them and down and to some extent above and behind.
The appendages are preserved in beautiful detail, there are five pairs on the head
and a battery of appendages behind and they're rather complicated actually not simple,
you can see here parts of individual appendages which look as if they might be used as legs.
Certainly these brightly coloured paddle-like parts of the appendages
were probably used in that way as paddles for locomotion,
but also by comparison with modern relatives of this animal, modern crustaceans,
these paddle-like structures some of them may have been used for respiration.
These large paddle-like areas very delicate would have maximized oxygen uptake
in the environment in which they lived and it's a very nice animal adapted to its environment.
