Comments on "the phylogeny of post-Palaeozoic Asteroidea (Neoasteroidea, Echinodermata)" by A.S. Gale and perspectives on the systematics of the Asteroidea.

Zootaxa, 2014
A new, morphologically based classification of extant asteroids with comments on select fossils was published by A.S. Gale. Research approaches used limited sampling, and much literature treatment is not accurate and therefore misleading. We review these concerns, seeking to clarify argumentation on differing interpretations.

Food and Feeding Mechanisms: Asteroidea

2020
This chapter is concerned only with the food and feeding mechanisms of asteroids. Organically rich sediment grains and then-associated micro- and meiofauna appear to be an important food resource for deep-sea asteroids. Food specialization is only linked to prey availability as some species exhibit a real food preference.

Notes on Cretaceous Asteroidea

Quarterly Journal of the Geological Society of London, 1940
Introduction The publication by the Palaeontographical Society of a monograph on the Cretaceous asteroids by Sladen and Spencer (1891–1908) and by the Royal Society of a paper by Dr. Spencer (1913) on the evolution of the same group might seem to have exhausted the subject for the time being. Very many of the starfish figured in the monograph,

Phylogeny and classification of the Asteroidea (Echinodermata)

Zoological Journal of the Linnean Society, 1987
Post-Palaeozoic asteroids share a large number of derived characters of the ambulacral column and the mouth frame, and constitute the crown group of the monophyletic group Asteroidea. This crown group is here called the Neoasteroidea (new subclass). The stem species of the crown group lived in the Permian or early Triassic and so the evolution of the ...
