Adololopas moyasmithae
Taxonomy
Adololopas moyasmithae was named by Campbell and Barwick (1998) [Endocranium poorly ossified. Dermal roofing bones not tightly sutured together, cosmine covered; bone B long and narrow, and with scalloped margins; bone I transmitting a lateral line canal from Yi to bone Z; no Y2 preserved, but judging from the position of 8 and the shape of the opercular, it must have been present; bones 4, 5 and 8 unusually long for a tooth-plated form of this age; snout well-ossified. Adult pterygoidal tooth-plates thick, with an open median suture and with 6-7 rows of teeth; new conical teeth added at ends of rows, and mounted directly on bone; mandibular tooth plates showing teeth added sufficiently deeply to be out of occlusion but growing up into occlusion as they increase in size; adult tooth-plates with thin primitive dentine and serrated edges along the posterior margins; palatal tooth-plates concave, and mandibular plates convex. Juvenile tooth-plates with six or seven rows of sharp teeth; continuous rings of enamel- or enameloid-covered primitive dentine around the posterior, lateral and mesial edges. Parasphenoid with ploughshare shape, pointed posterior extremity and closed buccohypophysial canal lying in its anterior keel. Dentary narrow; angular bone with a deep notch posteriorly for articulation of the surangular. Body short and rapidly tapering; scales similar in form to those of Chirodiptenis australis, but their size diminishes rapidly towards the tail and the dorsal margin.]. It is not extant. Its type specimen is ANU 49213, a partial skeleton (an incomplete specimen with part of the skull preserved). Its type locality is Paddys Valley, which is in a Frasnian intrashelf/intraplatform reef lime mudstone/shale in the Gogo Formation of Australia.
