Article title

Chasmops – a typical representative of the family Pterygometopidae (Reed, 1905) found in an aggregate mine in Mielenko Drawskie, West Pomerania Province, Poland

Languages of publication
The oldest trilobite being found so far in an aggregate mine in Mielenko Drawskie is the Cambrian trilobite Agnostus (Salter, 1864). In the area of the Drawsko Pomorskie District, it is possible to observe a wide range of Ordovician trilobites. Ordovician trilobites of order Phacopida (Salter, 1864) are to be found in this area quite commonly. The most frequently observed representative of the family Pterygometopidae (Reed, 1905) is a trilobite of the genus Chasmops from the Ordovician Period. It can be found in sedimentary rocks on sandy and stony fields throughout the whole Drawsko Pomorskie District.
