Nice finds, they could be paddle bones or just pieces of rock worn into interesting shapes by the energy of/in the beach.
Did you find them in a rock, sediment or loose in one area of the beach.
After looking at some paddle bones I think only one of your specimens is similar to what I thought they could be.
Nature often shapes rocks into interesting objects that resemble fossils.
I hope it's ok as I have attached some images of what I thought they could be.
Hi. I found this quite a while ago. I think mine is just a rock, but it looks identical to yours. Yours may be paddle bones, but I doubt it (although they do look a very simular shape.)
Hi fossilhunter, second image, the specimen on the right with a line along the middle of it.
Are you out collecting when it's safe to do so in your area?
Dan, that looks a bit like bone but it's hard to tell without the specimen in your hand, was it found on the Yorkshire coast?
