Découverte d'une nouvelle espèce du genre Ptilocrinus (Échinodermes, Crinoïdes pédonculés) au large de Terre-Neuve
Ptilocrinus atlanticus sp. nov. belongs to the family Hyocrinidae (Echinodermata, stalked Crinoidea). That new species is the first record of the genus Ptilocrinus in the Atlantic Ocean. Skeletal organization of the arms suggests that it has a taxonomic place halfway between the genus Ptilocrinus (e...

Ptilocrinus atlanticus sp. nov. belongs to the family Hyocrinidae (Echinodermata, stalked Crinoidea). That new species is the first record of the genus Ptilocrinus in the Atlantic Ocean. Skeletal organization of the arms suggests that it has a taxonomic place halfway between the genus Ptilocrinus (especially Ptilocrinus pinnatus from N.-E. Pacific) and the genus Anachalypsicrinus, only recorded from N.-E. Atlantic. Such a discovery confirms the phylogenic affinities between large hyocrinids of the eastern Pacific and those of the northern Atlantic. Geographic isolation of these two deep-sea provinces since the Uppermost Cretaceous took place after the differentiation of the two genera Ptilocrinus and Anachalypsicrinus. |
