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 brittle star assemblages. Here, we describe new ophiuroid material from the Late Oxfordian Bure Member as exposed in a construction site along the federal Highway A16 (Transjurane Highway) near Boncourt–Queue au Loup (Swiss Jura Mountains). The remains are exceptionally well preserved and partially… 

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

Brittle stars from the Lower Cretaceous of Patagonia: first ophiuroid articulated remains for the Mesozoic of South America

The first articulated remains of ophiuroids for the Mesozoic of South America are described from the Lower Cretaceous of Neuquén Basin, Argentina, and a transfer of Ophiopetra to the family Ophionereididae within the order Amphilepidida is proposed.

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

New Brittle Stars (Echinodermata, Ophiuroidea) from the Oligocene of the Mainz Basin, Germany

Two new species of ophiuroid are described from the Lower Oligocene of the Mainz Basin, based on microfossils extracted from the sieving residues of bulk sediment samples from a flush drill in Nierstein, Rhineland-Palatinate, which suggests deep sublittoral to shallow bathyal palaeodepths for the Niersteins Basin.

Phylogenomic Resolution of the Class Ophiuroidea Unlocks a Global Microfossil Record

An unusual echinoderm assemblage from the earliest Bajocian (middle Jurassic) of Luxembourg, with special emphasis on the ophiuroids (Echinodermata: Ophiuroidea)

Die Mehrheit der Stachelhautervergesellschaftungen aus dem Bajocium wurden aus Ablagerungen von Karbonatplattformen beschrieben. Im Nordwesten der Tethys haben diese Ablagerungen aussergewohnlich



The Oldest Representative of a Modern Deep-Sea Ophiacanthid Brittle-Star Clade from Jurassic Shallow-Water Coral Reef Sediments

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

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

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.

A new ophiuroid (Geocoma schoentalensis sp. nov.) from the Middle Jurassic of northwestern Switzerland and remarks on the family Aplocomidae Hess 1965

A new ophiuroid species from the Hauptrogenstein Formation (Middle Jurassic, Bajocian) of the Rehhag ridge near Schöntal, northwestern Switzerland, is described based on 34 specimens. The impression

Exceptionally well‐preserved brittle stars from the Pliensbachian (Early Jurassic) of the French Ardennes

Two new genera and species of ophiuroid, Inexpectacantha acrobatica new gen. et sp.

Brittle stars (Echinodermata: Ophiuroidea) in the German Bight (North Sea)—species diversity during the past 130 years

A fairly stable composition of brittle stars is represented in the inner German Bight during the past 130 years, and findings do not indicate sustainable changes in the species diversity over time.

Late Cretaceous-Early Palaeogene echinoderms and the K/T boundary in the southeast Netherlands and northeast Belgium —

A total of twenty-one genera and thirty-seven species (seven of them new) are recorded from the Campanian-Danian of Liege-Limburg and the Aachen area (Germany) and the geographic and stratigraphic distribution of this diverse echinoderm group is documented.

Sequence Stratigraphy of the Oxfordian and Kimmeridgian Stages (Late Jurassic) in Northern Switzerland

The Oxfordian and Kimmeridgian exposures of the Jura of northern Switzerland show a transition from a shallow-water carbonate platform to a deeper marine basin. The carbonate platform was well

New records and new species of Ophiuroidea (Echinodermata) from Lifou, Loyalty Islands, New Caledonia

This is a taxonomic account of the brittle stars found at the island of Lifou, Loyalty Islands, New Caledonia, in November of 2000, and three species and a subspecies are revised, one of them placed in a new genus.

Late Jurassic sea-level fluctuations in NW Switzerland (Late Oxfordian to Late Kimmeridgian): closing the gap between the Boreal and Tethyan realm in Western Europe

In Late Jurassic times, the Swiss Jura carbonate platform occupied the transition between the Paris Basin and the Tethys and thus connects the Boreal and Tethyan realm. Up to now, the lack of index
