Depth reconstruction based on the extrapolation to fossil assemblages of present-day depth ranges of closely related groups is one of the most widely used approaches in palaeobathymetry. Here, we assess the ophiuroid fauna of the Bajocian to Bathonian (Middle Jurassic) Hauptrogenstein Formation and coeval formations in Switzerland with respect to the depth ranges of extant members of the groups identified. In addition to previously known taxa, we describe three new species, one assignable to… 
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
Shallow-water brittle-star (Echinodermata: Ophiuroidea) assemblages from the Aptian (Early Cretaceous) of the North Atlantic: first insights into bathymetric distribution patterns
In spite of their excellent preservation potential and abundance, brittle-star microfossils are still an underexploited source of alpha-taxonomical data. Knowledge on the Lower Cretaceous fossil
Brittlestar diversity at the dawn of the Jenkyns Event (early Toarcian Oceanic Anoxic Event): new microfossils from the Dudelange drill core, Luxembourg
Abstract Ophiuroids, the slender-armed cousins of starfish, constitute an important component of modern marine benthos and have been used successfully in the exploration of (palaeo)-ecological and
On an unusual shallow occurrence of the deep-sea brittle star Ophiomyces delata in the Duncan Passage, Andaman Islands (Northern Indian Ocean)
TLDR
The present discovery of Ophiomyces delata represents the first report of this lineage at shallow depths since the mid-Jurassic, and the recently resurrected name for the family is replaced with the senior synonym Ophiohelidae Perrier, 1893.
An unusual assemblage of ophiuroids (Echinodermata) from the late Maastrichtian of South Carolina, USA
A small, albeit diverse, assemblage of dissociated ophiuroid ossicles, mostly lateral arm plates, from the upper Maastrichtian Peedee Formation temporarily (August 1998) exposed at North Myrtle Beach
A new ophiacanthid brittle star (Echinodermata, Ophiuroidea) from sublittoral crinoid and seagrass communities of late Maastrichtian age in the southeast Netherlands
TLDR
The small size and the exceptional preservation of a single articulated specimen partially wrapped around the stalk of a bourgueticrinine suggest that O. floorae n.

Early and Late Jurassic mudstones of Europe are rich in remains of the isocrinid Balanocrinus. Recently collected material from the Early Pliensbachian of Sedan (France), from the Oxfordian of
Brittle stars from the British Oxford Clay: unexpected ophiuroid diversity on Jurassic sublittoral mud bottoms
Abstract. Three new ophiuran species, Enakomusium whymanae n. sp., Aspidophiura? seren n. sp., and Ophiotitanos smithi n. sp., and an unnamed specimen assignable to the genus Dermocoma are

TLDR
A comparison with coeval shelf assemblages reveals that, at least in some of the analysed groups, significantly more extant families/superfamilies have endured in the deep sea since the Early Jurassic than in the shelf seas, which suggests that deep-sea biota are more resilient against extinction than shallow-water ones.

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.
New sea spiders from the Jurassic La Voulte-sur-Rhône Lagerstätte
TLDR
Combined evidence from depositional environment, faunal associates and recent analogues indicate that the La Voulte pycnogonids probably lived in the upper bathyal zone (ca 200 m), which suggests a relatively recent, possibly Mesozoic origin for at least three major extant lineages of pycnOGonids.

Pitfalls of paleobathymetric interpretations based on trace fossil assemblages
Trace fossils have been used widely as indicators of original water depth in paleoenvironmental studies, but most paleobathymetric interpretations in ichnology have been based on only a small number
Ecological Significance of the Arthropod Fauna from the Jurassic (Callovian) La Voulte Lagerstätte
TLDR
Converging lines of evidence from depositional environment and modern analogues indicate that this arthropod fauna probably inhabited a deep water setting most probably exceeding 200 m (= bathyal zone) under dysphotic or aphotic conditions, and sheds new light on the deep-sea colonisation by animal communities in the Mesozoic.
