Source term: oval and line, probably a bullroarer

On a saddle of Flat Rocks ridge above the Hawkesbury, north-east of Gunderman, one gallery carries a hundred and forty-five engraved figures and forty-nine grooves worn by the sharpening of axes. Frederick McCarthy numbered every mark in 1956 and worked down the list - possum, echidna, bird track, wallaby, a boomerang thrown at a rodent - and at number 30 wrote an oval and a line running from it, probably a bullroarer. If he read it right, this is the instrument shown rather than found: an outline pecked into sandstone on a ground he published as a Daruk ceremonial place. It carries no date at all, and an oval joined to a line is a thin thing to build on; the rock says nothing about who cut it, or for what.

(30) oval and line, probably a bullroarer

McCarthy 1956:53, Group 10 Series IV catalogue
Object
Engraved sandstone motif, not an object: a small oval with a line running from it, numbered 30 in McCarthy's Fig. 11 plan of Group 10 Series IV. No measurement is given for motif 30 in particular; the group's outlines run about half an inch wide and an eighth to three-sixteenths of an inch deep. Group 10 occupies a saddle on the main ridge and holds 145 engravings and 49 axe-grinding grooves.
Function
Not recorded.

Source confidence
low Gunderman, New South Wales, the public locality at the south-western end of Flat Rocks ridge. The ridge runs about ten miles north-east from here to Mangrove Creek and McCarthy publishes no coordinate for Group 10's saddle, so this is a deliberately generalised public anchor rather than a site coordinate - consistent with the atlas's handling of Australian rock-art points (KTBULL2026-001, BPHED2026-001) for cultural-site sensitivity.
