Slimonia is a genus of eurypterid, an extinct group of aquatic arthropods. Fossils of Slimonia have been discovered in deposits of Silurian age in South America and Europe.

Slimonidae (the name deriving from the type genus Slimonia, which is named in honor of Welsh fossil collector and surgeon Robert Slimon) is a family of eurypterids, an extinct group of aquatic arthropods.

Slimonia may have had a broadly analogous hunting strategy, identifying and homing in on targets visually, capturing and subduing prey in the water column with their robust prosomal appendages, then dispatching their victim using their robust chelicerae.

Here, I describe a pair of exceptionally preserved che-licerae in a specimen of Slimonia from the Yale Peabody Museum of Natural History collec-tions and compare the available morphology with that reported by Laurie (1893).

This fossil dates back to around 430 million years ago. It shows the tail of the eurypterid Slimonia acuminata curved in such a way that the tip, known as the telson, is parallel to its body. In life, this telson could have reached as far as, or even farther than the animal’s mouth.

Salteropterus is classified as part of the Slimonidae family of eurypterids, within the Pterygotioidea superfamily, alongside Slimonia. [5] Slimonidae was first erected as a taxon by Nestor Ivanovich Novojilov in 1968 to contain Slimonia, previously considered part of …

Slimonia is a relatively large eurypterid, attaining lengths of 70–80 cm, with eyes on the anterolateral margins of a rectangular carapace, small chelicerae, robust walking legs with a serrated distal margin, genital appendages with three segments, and a laterally expanded telson.

May 30, 2017 · Some of the marine creatures had a thin, serrated spine on the tip of their tail — and that tail was surprisingly flexible, based on a 430-million-year-old fossil found in Scotland. Slimonia...
