Carcharhinus coatesi (WHITLEY, 1939)
Description:
a) after Whitley, 1939:
Erect, compressed teeth in upper jaw, each with one large central cusp (not serrated to tip and sometimes not serrated at all), notched, with six or seven strong serrations on one side of the base and on the other a less strongly serrated convex edge. Lower jaw teeth curved, flexuous, acute, sloping outwards, entirely without serrae.
b) after White, 2012:
Teeth relatively few, in 24–26/23–25, or 47–51 total rows (both jaws, n=6). Teeth not arranged in diagonal files, no toothless spaces at symphysis. Teeth highly differentiated in upper and lower jaws and along jaws. Tooth formula (n=6): upper jaw 11–12 + 1–2 + 11–12, lower jaw 11–12 + 1 + 11–12. Upper anterolateral teeth with moderately broad, oblique, blade-like cusps; lateral margins deeply notched; medial margins convex basally, nearly straight distally; several large cusplets basally on lateral margin; medial margin with coarse serrations, lateral margin usually with some coarse to fine serrae; basal cusplets smooth, without serrations. Lower anterolateral teeth with narrower, slightly oblique cusps; lateral margins notched, with several small to large, smooth basal serrae; medial margins concave; both margins smooth distally, often with some fine serrations basally.
Material: TL 70 cm, female, Australia, size of the jaw: 9,5 cm x 6,3 cm (Pre-Convention specimen)
