Research Abstract |
We observed the fossilized chemosynthetic assemblages found along the coastal area of northwestern Leyte, Philippines where Pliocene to Pleistocene marine sediments are exposed. This is the first discovery of fossil cold-seep assemblages in Southeast Asia. The assemblages show considerable variations in their modes of fossil occurrence in association with 13C-depleted authigenic carbonates indicating that they depended on methane seepages. In situ Calyptogena and large lucinid colonies have been discovered from the Cambantug Point and the Antipolo Point, respectively.
