Ophiurites crinitus is a fossil brittle-star species which passed largely unnoticed since its original description. In this paper, we redescribe the type material of O. crinitus with the aim to put it into the context of modern ophiuroid systematics, and propose the new genus name Ophiosternle to replace the invalid Ophiurites. The re-assessed species is shown to be a member of the extant deep-sea family Ophiacanthidae, articulated fossils of which are extremely rare. It presents greatest… 
A remarkable example of a Late Jurassic shallow-water ophiuroid assemblage from the Swiss Jura Mountains
Although much effort has been put into attempts to unravel the Mesozoic ophiuroid fossil record, surprisingly little attention has been paid to the geological history of family-level compositions of
Temporary expansion to shelf depths rather than an onshore-offshore trend: the shallow-water rise and demise of the modern deep-sea brittle star family Ophiacanthidae (Echinodermata: Ophiuroidea)

TLDR
It is speculated that the large-scale ophiacanthid invasion of shelf environments around the Triassic-Jurassic boundary was initiated by a change from thermohaline to halothermal circulation, attenuating the thermal stratification of the water column and thus providing opportunities for enhanced vertical migration of marine taxa.
Brittle-star mass occurrence on a Late Cretaceous methane seep from South Dakota, USA
TLDR
The mass occurrence described herein is an unambiguous case of an autochthonous, dense ophiuroid community that persisted at a particular spot for some time and represents a true fossil equivalent of a recent ophi Kuroid dense bed, unlike other cases that were used in the past to substantiate the claim of a mid-Mesozoic predation-induced decline of ophiurid dense beds.
Species That Fly at a Higher Game: Patterns of Deep–Water Emergence Along the Chilean Coast, Including a Global Review of the Phenomenon
TLDR
Analysis of occurrence data of more than 1000 invertebrate species along the Chilean coast revealed patterns from 28 species and six genera with similar longitudinal and bathymetric distribution along the entire Chilean coast.

New ophiacanthid brittle stars (Echinodermata: Ophiuroidea) from the Upper Triassic of Japan: first insights into the origin and evolution of an extant deep-sea group
TLDR
The first cladistic analysis of the Ophiacanthidae including all extant genera suggests L. gracilispina holds a basal, but not the basalmost, position within the family, forming a sister group with the extant Ophiomedea and Ophiopristis to the other ophiotominids except for Ophiologimus.
Who's who among baby brittle stars (Echinodermata: Ophiuroidea): postmetamorphic development of some North Atlantic forms
TLDR
The ophiuroid skeleton continues to develop well beyond metamorphosis and small juveniles often lack many of the characters used to identify adult specimens, so accurate descriptions of postlarvae and their development are therefore necessary to match them to their adult conspecifics.
Ophiuroid phylogeny and higher taxonomy: morphological, molecular and palaeontological perspectives
TLDR
A cladistic analysis of the class Ophiuroidea at subfamily level is presented based on a morphological data base of 43 characters, which identifies Ophiocanopidae as sister group to other extant ophiuroids, which themselves fall into two major groups.

TLDR
The use of isolated fossil lateral arm plates for taxonomic interpretations in ophiuroid micropalaeontology, including species identifications and the creation of new taxa, is endorsed, providing that descriptions are based on pristinely preserved adult proximal LAPs.
