Today’s photograph is of an unusual association of an odontopleurid trilobite and a diplobathrid crinoid that was collected from the Ordovician of Kentucky.
The trilobite(Acidaspis sp) is seen on the top most brachial of the crinoid(Reteocrinus sp.), in the photograph.
I am still trying to determine if the assemblage represents thanatocoenosic(death assemblage) preservation of a community, or post mordem predation by the trilobite, and then preservation.
Anyone have any thoughts?
