Trinucleidae
Trinucleidae is a family of small to average size asaphida, asaphid trilobites that first occurred at the start of the Ordovician and became extinct at the end of that Period (geology), period. It contains approximately 227 species divided over 51 genera in 5 subfamilies. The most conspicuous character is the wide perforated fringe of the head. Description Trinucleids have a relatively large headshield, that is characterized by a highly vaulted pear-shaped glabella, separated by deep furrows from the cheeks that are often vaulted too, but less so. To the front and sides of this tri-nucleate centre is a wide seam (or fringe), that often inclinates towards the outer margin, and is perforated by funnel shaped pits. These pits are only in one row at the front in the first occurring genera, irregularly distributed in early species, but in later species these are largely arranged in several rows parallel to the margin, and in arches more or less perpendicular to the margin.

Shropshire
Shropshire (; alternatively Salop; abbreviated in print only as Shrops; demonym Salopian ) is a landlocked historic county in the West Midlands region of England. It is bordered by Wales to the west and the English counties of Cheshire to the north, Staffordshire to the east, Worcestershire to the southeast, and Herefordshire to the south. A unitary authority of the same name was created in 2009, taking over from the previous county council and five district councils, now governed by Shropshire Council. The borough of Telford and Wrekin has been a separate unitary authority since 1998, but remains part of the ceremonial county. The county's population and economy is centred on five towns: the county town of Shrewsbury, which is culturally and historically important and close to the centre of the county; Telford, which was founded as a new town in the east which was constructed around a number of older towns, most notably Wellington, Dawley and Madeley, which is today th ...
