Hi all. I have this specimen i bought fra a dealer in western europe It's from the Lesmahagow in scotland. I bought it as a Slimonia, but was later advised on facebook that it's in fact a ceratiocaris. What do you guys here think? I'm pretty convinced it's a ceratiocaris.

Many important collections of Silurian arthropods and vertebrates have been made near Lesmahagow since the mid to late 1800's.
