Please help id fossils (Yorkshire coast UK)

Hi, Could anyone possibly shed any light on what any of these fossils are? http://www.scarlettmist.com/FOSSIL/fossils.htm Obviously some are wood, others are shells etc but I'd love to know more details, I don't have any good enough books to id them from (neither does my local library) and I've googled for hours and am still not much wiser! I have loads more odd fossils too which I have not photographed as yet. My email address is on the webpage linked above, Thanks for any help,

Fossil 1: ?

Fossil 2: Burrow of some sort. (Planolites?)

Fossil 3-5: Coral

Fossil 6: ?

Fossil 7: Clam (Pelecypod). It appears to be a cast of the interior of the shell.

Fossil 8: Snail (Gastropod)

Because of heavy wear, the fossils probably aren't identifiable as to Genus-species.

Phillip Bigelow's identifications in this thread are likely accurate. I would add that the specimen listed as Fossil #1 could be a rudist, an extinct bivalve.

Number 1 looks like it might (and I emphasize 'might' be a fragment from the shell of a very large pecten. Pecten are bivalve mollusks. The shell used in the logo for Shell Oil in the US is a pecten. I have a specimen of Chesapecten from the Miocene of Maryland that is broken into fragments some of which look much like your fossil. But about half the size. The complete Chesapecten is about 10cm across. I'd guess that if your fossil is a pecten fragment, the complete shell might be 20cm or more across.

It dawned on me after I posted that probably the best person to consult regarding rudists is Dr. Thomas Steuber through his web page at http://www.ruhr-uni-bochum.de/sediment/steuber.htm ; Dr. Steuber is a leading rudist specialist. Rudists, of course, appear in the geologic record during the late Jurassic

Thank you to everyone who has replied, I am going to read your replies more closely now and have a look at the web links too. I had thought that #3 & 5 were tree bark or wood of some sort, I had not considered that they could actually be corals. I had no real idea at all what #1 could be, I am embarrased to admit that I initially thought it might be plant or leaf stems! Thank you once again for all your help, it is much appreciated

I was thinking, along with the rudist idea stated elsewhere in this thread (and if I'm mistaken on that identification, it will, of course, be one of the 'rudist' paleontological awakenings I've ever experienced...), that the specimen could possibly be a fragment of a Pinna (Carboniferous to Recent), a Mytiloid bivalve of the Superfamily Pinnacea.

Man, It is quite important to know about the age of the rocks where you have those fossils from. However, it seems to me that photo #1 is some kind of branched coral. Try to cut and polish transversally a 'branch'; than you may see much more. Photos #3, #5 and #6 are definitely sponges. It is hard to find out more about their taxonomy because there is no complete paper-work which can be used for determination. The pore pattern in photo #6 is similar to genus Cribrospongia (Upper Jurassic) but is difficult to precise. Nevertheless, the right determination can be done only in thin section or microscopic samples of the skeletal structure. Photo #4 seem to me as a bunch of Serpulid (worm) traces. Good luck and keep in touch.
