A new specimen of the synziphosuran Limuloides limuloides (Woodward, 1865) from the Silurian of the Welsh Borderland

Key Points

This research aims to describe a new specimen of Limuloides limuloides from the Silurian period.
Described an articulated prosoma and opisthosoma from the Aston Mudstone Formation.
Collected the specimen from a new locality near Aston Dingle, Shropshire.
Compared the specimen with previous known samples to assess its morphology.
The specimen represents the third known Limuloides limuloides in the Wenlock period.
The prosoma and opisthosoma are well-preserved but lack a telson.
The specimen adds to the understanding of the rarity and distribution of this species.

Abstract

ABSTRACT About three dozen specimens of the synziphosuran Limuloides limuloides (Woodward 1865) have been collected from Silurian strata in the Welsh Borderland since 1855, making it a rather rare component of the fauna. Most of these specimens are incomplete, mainly isolated prosomas. Here, a new specimen of the species is described from a single part (no counterpart). It is an articulated prosoma and opisthosoma, lacking a telson, and in apparently full relief. It comes from the lowermost Aston Mudstone Formation (Wenlock: Homerian, probably nassa zone), from a locality close to Aston Dingle near Bishop’s Castle, Shropshire, which is a new locality for L. limuloides , and the specimen is only the third known for this species in the Wenlock.
