Contraconus scotti

Conus (Contraconus) scotti (Petuch, 1994)

Description ⁽¹⁾: Shell of small to below-average size for genus, slightly stocky, broad across shoulder, with moderately-high, stepped spire; shoulder sharply-angled, edged with wide, rounded carina; spire whorls concave, slightly canaliculate; body whorl heavily ornamented with very numerous, fine spiral cords and with cords on anterior third being largest; aperture narrow, widening toward anterior end.

Holotype: UF66446, Length 58 mm.

Type Locality: Griffin Pit Unit (lower beds) from Bergeron Star pit, US Highway 27 south of South Bay, Palm Beach County.

Remarks: Contraconus scotti is the immediate descendant species of C. tryoni (Heilprin, 1886) (Plate 96, Figures A, B) from the older, Caloosahatchee Fauna, and is confined to the lower beds ("yellow sands") of the Griffin Pit Unit. The new species differs from its well-known ancestor, C. tryoni, in being a much smaller, shorter, and stockier shell with a lower, more canaliculate spire, and in lacking heavily-beaded, heavily-coronated early whorls.

Etymology: Named for Dr. Thomas Scott, Assistant State Geologist, Florida Geological Survey.
