Here is a super nice preserved exuvia of Olenellus gilberti from Nevada. The trilobite offers a very detailed preservation and a wonderful contrast and colour. Also the hypostome is visibile. This piece shows very good the mode of moulting on Ollenelid - Trilobites that do not have a facial suture jet.
