A DESCRIPTION OF ADDITIONAL VARIATION SEEN IN THE SCALE MORPHOLOGY OF THE FRASNIAN THELODONT AUSTRALOLEPIS SEDDONI TURNER AND DRING, 1981

WA Museum Records and Supplements | Updated 1 decade ago

Abstract - Isolated scales are referred to the thelodont Australolepis seddoni from the (Frasnian) Gneudna Formation, Carnarvon Basin, Western Australia. A total of 670 scales was examined in comparison to the original sample of 60 scales, and it is considered that the majority of these scales represent morphological variation within A. seddolli. The scales were then assigned to different body regions based on their morphology. In addition to A. seddoni scales, two other scale types were recognized and these were referred to the genus "Skamolepis." The presence of this genus in the Gneudna Formation suggests a close link between the faunas of Western Australia and central Iran.
