Comments
Nice specimen of this interesting trilobite. The species name titan refers to this species being significantly bigger than the Czech typespecies Declivolithus alfredi. The distinctive head-shape of this suspension feeder shows this trilobite was probably adapted to fast swimming.
Here's a paper describing the new species and the type locality: http://www.geology.cz/bulletin/fulltext/1649_Fortey_170930.pdf
