Early crinoid faunas, characterised by a range of stem lengths and arm branching patterns, have provided vital clues regarding ancient marine ecosystems and the processes of niche partitioning.

The Crinoidea, a class of marine echinoderms, have long captivated palaeontologists as one of the most enduring and diverse components of the marine fossil record. Their evolutionary history spans ...

Sticking out of the wood and flowing in the water were two “unusual,” feather-like creatures attached to the rotting material by thick stalks, researchers said. Genetic testing confirmed the stalked ...

Researchers discovered Endoxocrinus kexuei, a new crinoid species, in the South China Sea, living on cold seep habitats over 2,700 feet deep.

The spatial analyses such as principal component analysis (distribution variability of crinoid host and associated crustacean fauna), metric multidimensional scaling analysis (distance matrix of ...

The crinoid has between 20 and 22 arms that can reach up to 5.5 inches long, according to the study. The animal’s stalk is shorter than its arms, about 2.5 inches long, researchers said.
