Mainefossils Posted February 25, 2021 Share Posted February 25, 2021 Fossil forum, This is another specimen from the Leighton Fm. I had two possibilities, Lingula scobina and L. lewisii, which I found mentioned in this paper https://repository.si.edu/bitstream/handle/10088/14399/1/USNMP-45_1985_1913.pdf, and which I further researched. The main problems I have with these two species are that L. scobina has different surface sculpture, and L. lewisii is an English species. Any further guidance or suggestions? Here are some pictures of it (internal mold on the left, external on the right): The more I learn, the more I find that I know nothing.
