Emsian (Early Devonian) Tetracorals (Cnidaria) From Grattai Creek, New South Wales, Anthony Wright
Emsian (Early Devonian) Tetracorals (Cnidaria) From Grattai Creek, New South Wales, Anthony Wright
Anthony Wright
The tetracoral species Phillipsastrea scotti sp. nov. and Trapezophyllum grattaiensis sp. nov. are described from strata assigned to the middle Emsian (nothoperbonus to inversus conodont zones: Early Devonian) part of the Cunningham Formation at Grattai Creek, west of Mudgee, N.S.W. For comparison with the former, Phillipsastrea oculoides, from the Early Devonian (late Pragian or early Emsian) Garra Formation in the Wellington area of N.S.W., is revised on the basis of the type material; new longitudinal thin sections show indisputable horseshoe dissepiments and trabecular fans in this species.
New Genera Of Early Devonian Calceoloid Corals From Australia And France, Anthony Wright
New Genera Of Early Devonian Calceoloid Corals From Australia And France, Anthony Wright
Anthony Wright
Two new Early Devonian genera and species of the family Calceolidae, phylum Cnidaria, are erected; these are Richtereola disruptus n. gen., n. sp., from the Emsian (perbonus conodont zone) of the Taemas area, NSW, Australia and from the Emsian Izarne Formation (gronbergi conodont zone) of the Montagne Noire, southern France; and Savageola unicus n. gen., n. sp. from the Lochkovian (eurekaensis conodont zone) Mandagery Park Formation at Manildra, NSW, Australia. These taxa are essentially defined on opercular characters; well-preserved opercula are essential for confident generic assignment of calceoloid material. Savageola is known only from eastern Australia, but Richtereola is known …
