Hi, this is a fossil, interesting find infact. This is the stem of a Crinoid, an ocean dwelling animal that many mistake for a plant.

Hello and welcome to the forum. Yes, this is part of a crinoid stem. The geology is Oxford Clay Formation, Mudstone, Siltstone And Sandstone. Sedimentary Bedrock formed approximately 156 to 165 million years ago (Jurassic. Unfortunately, the photo of the end plate (crinoids are made up of plates or 'ossicles') is not clear enough for me to give you a name for it.

Pete, I think Pentacrinites is too old(Sinemurian) but probably Isocrinus sp
