概要 |
An ammonite first discovered from Curaçao is described as Parapuzosia n. sp. (?) which is allied to P. daubreei (GROSSOUVRE), from the Santonian of France, on one hand and to P. bocsei SCOTT and MOORE..., from the Campanian of Mexico and Texas, on the other. On this occasion remarks are given on Parapuzosia with some revision of the species concerned. Snstiniceras is separated as a distinct genus from Parapuzosia. Appendix: The stratigraphic position and age of the first ammonite found on the island of Curaçao (Netherlands Antilles) are discussed. In spite of tectonic and stratigraphic complications, it is concluded that the ammonite bearing formation is of Campanian or Maastrichtian age, subject to the correctness of the age assignments of Pseudorbitoididae as given in the literature.続きを見る
