Here is a rare Czech Duslia insignis that comes practically from the type locality.
Duslia is a Trilobite like soft body arthropod. This fossil shows a good and detailed preservation. Even the fine cilia on the body rim are clearly preserved.
This Duslia insignis from the Czech republic has a size of about 97mm.
This specimen is virtually complete what is not common from this site. This fossil site in the Letná formation has a difficult joint system. That makes is hard to extract larger and complete fossils from this exposure.
Also Jahn in 1893 had it not easy to obtain finally complete specimens from that site.
This specimen is a good and rare showcase fossil.
