Description: Well-preserved example of a member of the Order Asaphida, Family Trinucleidae. The cephalic pits (fenestrae) are evident, the means by which this trilobite filtered detritus from the seafloor. The trilobite presumably hovered at the seafloor, using its legs to kick up particulates which then passed through the cephalic ring. Overall, a fine example of the taxon, rarely offered with this degree of preservation. There is also a small partial present near the edge of the matrix as well.
