Emily H Yokes Department of Geology Tulane University Orleans, LA 701 18, U S A ABSTRACT Only three species of Spondylus have been collected in the Neogene strata of the northern Dominican Republic These include: Guppy which is largely confined to the more shallow facies of the late Miocene-early Pliocene Gurabo Formation; and giimanomocon 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 bostiychiles and two of giimanomocon) have been collected in the late Miocene Cercado Formation hostryclutes RESUMEN Se han colectada solo tres especies de Spondylus en los stratos Neogenos del norte de la Republica Dominicana Estas incluyen: mayor parte restringida a las facies mas someras de la Formacion Gurabo del Mioceno tardio al Plioceno principle; y S giimanomocon Brown y Pilsbry, por la mayor parte restringida a las facies coralinas de la Formacion Gurabo, y del Miembro Mao Adentro de la Formacion Mao La lercera especie esta representada por un solo especimen de lucasi Maury de la Formacion Gurabo No se encuentran especimenes de Spondylus en la Formacion Baitoa del Mioceno principio y solamente Ires (uno de S boslrychiles y dos de gumanomocon) se han colectado en la Formacion Cercado del Mioceno S bostrychnes Guppy, por la tardio INTRODUCTION This study is of the material utilized herein a small contribution to the on-going project on the Neogene fossils from exposures in the Cibao Yalley, northern Dominican Republic (Text-fig 1) The geological setting and the history of the Dominican Republic Project have been thoroughly covered by several authors (see Saunders, Jung, and Biju- Duval, 1986; Jung, 1986; E Yokes, 1989; H Yokes, We are grateful to Dr American Museum of Natural History, New York, and Dr George M Davis and Ms Elena Benamy, Academy of Natural Sciences, Philadelphia, for the loan of type material, and to Dr Thomas R Niles Eldredge, Waller, U S National Museum of Natural History, and Dr Gary Rosenberg, Academy of Natural Sci- ences, Philadelphia, for reviewing the manuscript 1989) The material upon which this paper is based was collected by both the the Naturhistorisches Museum team of John Saunders and Peter Jung, and by the authors, as has been documented in the aforementioned papers For information on localities, stratigraphy, and ages, the reader is referred to the first work in this series: Saunders, Jung, and Biju-Duval (1986) Basel ACKNOWLEDGMENTS This study owes an immense debt of gratitude to Peter Jung, of the Naturhistorisches Museum Basel, who photographed and measured all of the type material for the species of Spondylus Linnaeus, 1758 that are involved His labors made the remainder of the work much less time-consuming In addition, he and John Saunders led the team that collected much NMB BIOSTRATIGRAPHY AND PALEOECOLOGY As there are but three species of Spondylidae Dominican Republic beds, and one of these is in the repre- sented by a single specimen, not a great deal of infor- mation can gleaned from their occurrence The most abundant species is S bostrychites Guppy, 1867, and from all evidence it followed a life-style unlike the vast majority of living spondylids, which attach to dead The bulk of the material comes from beds that, on the basis of other molluscan species present, we think of as "shallow-water Gurabo" (see E Yokes, 1989, p 21), with water depths of about 20 to 50 m From all ap- corals or other hard substrate for 5' bostrychites pearances the specimens of S bostrychites were not attached but lay "floating" in the fine silty sediment Bulletin 339 This quiet environment permitted the growth of long dehcate spines (see Text-fig 2) The other species for which we have enough material to consider is the more massive S gumanomocon Brown and Pilsbry, 1913, which is found primarily in the coralline facies of the Mao Adentro Member idently lived in the Gurabo Formation and of the Mao Formation more normal spondylid It the ev- fashion, attached to dead coral ABBREVIATIONS OF REPOSITORY INSTITUTIONS The following abbreviations for repository institu- tions are used in this paper: ANSP: Academy of Natural BMNH: British Museum (Natural History), London, England, U.K Most of the records of these two species are from the Gurabo Formation and the Mao Formation, but the occurrence of both is more dependent on environment than on time, as there is one specimen of S bostrychites and two of S gumanomocon from the Cer- NMB: cado beds One of the specimens of gumanomocon 16853, which is just upstream is from locality from the mouth of Arroyo Bellaco, in the Rio Cana drainage, where a very large coral reef is located (loc TU 1422; see Saunders, Jung, and Biju-Duval, 1986, text-fig 15 [loc TU 1282 is at the mouth of Arroyo Bellaco and TU 1422 is off the map]) No specimens of any species ofSpondylus Linnaeus, 1758 are known from the Baitoa Formation It is assumed that this is due to the very shallow-water nature of this formation The facies of the Baitoa is extremely similar to the shallow-water Cercado Formation, where specimens of Spondyhts are almost non-existent Throughout the Caribbean, species of Spondylus occur in other early Miocene beds that are correlated with the Baitoa Formation USNM: NMB Sciences, Philadelphia, PA, U.S.A

all tropical and subtropical marine waters The shell is highly variable in shape and ornamentation to the extent that no two specimens of a species are entirely alike The variation in shape is due to the nature of the surface to which the right valve becomes attached, but the surface ornament is influenced by the environment in which The shell spines are it is growing produced by extensions of the
