The new genus and species of surgeon fish, Glarithurus friedmani (Acanthuridae), from the Lower Oligocene (Rupelian) of Kanton Glarus, Switzerland, differs from all other acanthurid fishes, fossil and extant, by ...
Kionaster petersonae, n. gen. and sp., from the Miocene Chipola Formation of Florida, is the first-known fossil member of the extant family Asterodiscididae Rowe. Although abactinal and marginal expressions clear...
The internal, multi-element skeleton of echinoderms can differentiate almost as much as that of the vertebrates. The implied probability of post-mortem disarticulation was bypassed in pelagic species, whose ca...
The morphology of Gymnodiadema, until now incompletely documented from a single poorly preserved individual from the Callovian of Portugal, is clarified based on a new species from the Bajocian of Morocco. The ne...
After their near-extinction around the end of the Permian, crinoids recovered during the Triassic and re-occupied almost all ecological niches they had held in Palaeozoic times. Triassic crinoids comprise 33 g...
The asteroid fauna from the Late Oxfordian marls (bifurcatus Zone, stenocycloides Subzone) of Savigna includes 11 taxa, distributed between 8 families, of which 1 (Plumasteridae) is new. A goniasterid of distinct...
The holasteroid Echinocorys is a common, robust echinoid in the Upper Cretaceous–Danian Chalks and limestones of northern Europe. It formed hard substrates that were infested by a variety of encrusters and borers...
A succession of clays with thin shell beds from the French Ardennes, dated to the late Early Pliensbachian Davoei Zone and yielding abundant well-preserved remains of all five extant classes of echinoderms, is de...
The stereom microstructure of columnal latera in various articulate crinoids is examined to ascertain its potential application in phylogenetic studies. Most show either a poorly ordered labyrinthic stereom or...
A new species of early Hauterivian (Early Cretaceous) astropectinid starfish, Pentasteria? splendida, is recorded from strata assigned to the Endemoceras amblygonium ammonite Zone at Engelbostel, near Hannover (n...
The first articulated ophiuroids to be recorded from Neogene deposits in the southern North Sea Basin are described as a new species, Ophiura paucilepis, based on two discs with portions of proximal arms preserve...
Encrinus liliiformis is a well known crinoid from the middle Triassic Muschelkalk of Europe. A statistical analysis of crown shape was conducted in order to quantify possible differences in crown morphology of E.
Crinoid cirri are generally considered primarily as structures that anchor the animal to the substrate; however, a swimming function for cirri has also been suggested. Most notably, it has been claimed that an...
The Erratum to this article has been published in Swiss Journal of Palaeontology 2012 132:s13358-012-0046-7
Coincident with the end-Ordovician (end-Katian for crinoids) biodiversity crash, crinoids from Anticosti Island, Quebec, experienced a statistically significant reduction in body size, an evolutionary trend te...
