Neogene Paleontology in the Northern Dominican Republic

Résumé du livre

Only three species of Spindles have been collected in the Neogene strata of the northern Dominican Republic. These include: S. bostrychites Guppy, which is largely confined to the more shallow facies of the late Miocene-early Pliocene Gurabo Formation; and S. gumanomocon Brown and Pilsbry, which is largely confined to the coralline facies of the Gurabo Formation and the Mao Adentro Member of the Mao Formation. The third species is represented by a single specimen of S. lucasi Maury from the Gurabo Formation. No specimens are known from the early Miocene Baitoa Formation and only three specimens (one of s. bostrychites and two of S. gumanomocon) have been collected in the late Miocene Cercado Formation.
