Did Hotcrossbunodon ever make it as far as the ICZN? I know that when the
name was first floated in the pub, everyone else pointed out that the namer
would appear to be a complete wanker. I thought the matter ended there.

The fossils from Lightning Ridge are recovered by opal miners (with only a
few excaptions) and all are working in the Albian Griman Creek Formation.
It is not possible to assign any fossils from this unit to anything other
than Albian because the provenance of each specimen is so poorly known. As

received the attention of better speciemsn from Andamooka, White Cliffs or
