Good Afternoon,
I am new to this forum and I thought I may use the fossil ID service. I had a trip to the Jurassic Coast at Lyme Regis, England just after a storm and I snorkeled the coast as there always a wealth of fossils just out of reach under the waves. I found this strange item and had it ID'd locally as a possible Ichthyosaur paddle bone but I am unsure and think it may be just a geological formation. Marine worms have been making it their home and burrowing in which I haven't removed the remnants yet. The scale on the measure is in cm. Any second opinions are most welcome.
