U-Pb zircon ages from the southwestern Karoo Basin, South Africa—Implications for the Permian-Triassic boundary: COMMENT

[Fildani et al. (2009)][1] proved the Permian and Triassic age of the Ecca Group. However, the claim of providing “the first evidence of a marine Permian-Triassic (P-T) boundary in the Karoo Basin” ([Fildani et al., 2009][1], p. 719) is doubtful. Fildani et al. referred repeatedly to the Ecca
