A new asteroid genus from the Carboniferous of Ireland and its phylogenetic position and palaeoecology

Research output: Contribution to journalArticlepeer-review


Fandasterias facetus n. gen. and sp is described from the Tournasian of Ireland. Based on phylogenetic analysis incorporating conservative ambulacral column patterns, basin arrangement and the internal odontophore are homoplastic, and Fandasterias is not assignable to the crown-group, although arguably at least one Late Palaeozoic asteroid is. Promopalaeaster and Fandasterias might have been functionally similar, but both represent extinct lineages not ancestral to extant asteroids. -from Author
