I am sure you will find your own crinoid stem some day, you have plenty of collecting time in front of you.

..... it looks so like a starfish, i really should get better at recognising fossils and i should use there latin names (if they have) and thank you for correcting me about the crinoid stem if you didn't i would still think they are starfish (i kinda should have guessed it wasnt as star fish are to brittle normaly to be like that)

They do look very similar. The first one I found I thought was a starfish, that was several years ago now, this summer I will find that specimen in Sweden, it is in storage there ready to come back and catalogued into the collection. I would recomend this book: http://www.amazon.co.uk/DK-Handbook-Fossils-David-Ward/dp/0751327964 Very good for fossil ID at the start.

basically it is a star fish,early echinerderms

Yes, same group, so are similar.

thanks for the book recomendation i will look into getting it

Oh and Welcome to the forum wegener

I sense the need for some geekery here! Echinodermata is broken up in 5 main groups, Echinoidea (echinoids- sea urchins), Asteroidea (asteroids- 'starfish/sea stars'), Crinoidea (crinoids- sea lilies), Holothuroidea [will have to check the spelling] (sea cucumbers), I sense the need for some geekery here! Echinodermata is broken up in 5 main groups, Echinoidea (echinoids- sea urchins), Asteroidea (asteroids- 'starfish/sea stars'), Crinoidea (crinoids- sea lilies), Holothuroidea (holothuroids- sea cucumbers), Ophiuroidea (ophiuroids- brittle stars). Only echinoids and crinoids fossilise readily, as they have hard parts on the outside as well as the insie, whereas the others only have seperate internal skeletons that don't join together so unless you're in a Laagertatte you're unlikely to find any complete ones, just isolated elements.

Nice geekyness!

Some of the finds -

That wicki stat has been updated and the understanding of these things are now an open book, ive recently found that what i thought where rogose coral are infact Stromatoporoid

Hehe that wasn't from Wiki, that was from my Palaeontology lecture for the world leader in fossil Echinoderms!

Stromatoporoids are a type of sponge and one of the most important Palaeozoic reef-builders, but they can look similar to many types of coral in thin and hand specimen. They were allied closer to corals in the past as well I think, things are changing a lot these days in taxonomy with all the genetic studies being done in recent years.
