Conference Paper
Degree of femoral neck anteversion distinguishes extinct sloth genera from each other, particularly when analyzed in combination with femoral neck angle. These data have been previously analyzed using a comparative sample including only extant sloths, which limits functional interpretations. Here, we analyze both femoral neck anteversion and femora...

While trends in tropical deforestation are alarming, conservation biologists are increasingly recognizing the potential for species survival in human-modified landscapes. Identifying the factors underlying such persistence, however, requires basic ecological knowledge of a species' resource use. Here, we generate such data to guide conservation of...

Full-text available
Raptor roosts, as accumulations of expelled pellets and nest material, serve as archives of past and present small mammal communities and could therefore be used to track invasive species population dynamics over time. We tested the utility of this resource and added new information towards reconstructing the phylogeographic history of a globally i...

Sloths were among the most diverse groups of land vertebrates that inhabited the Greater Antilles until their extinction in the middle-late Holocene following the arrival of humans to the islands. Although the fossil record of the group is well known from Quaternary deposits in Cuba, Hispaniola, and Puerto Rico, remains from older units are scarce,...

Parocnus dominicanus sp. nov. represents a new species of megalonychid ground sloth from the Altagracia Province of southeastern Dominican Republic. Specimens of multiple individuals, including one associated partial skeleton, were recovered from two separate underwater caves in the Parque Nacional del Este through collaborations with museums and c...

Ancient biomolecule analyses are proving increasingly useful in the study of evolutionary patterns, including extinct organisms. Proteomic sequencing techniques complement genomic approaches, having the potential to examine lineages further back in time than achievable using ancient DNA, given the less stringent preservation requirements. In this s...

Conference Paper
Full-text available
Antillothrix bernensis, an extinct platyrrhine primate from the Dominican Republic, has been under intensive study following a series of new finds from two flooded cave sites. To date, three nearly complete crania and one mandible have been described, but none of them preserve the anterior dentition. This study reports the first discovery of Antill...

Se realizara un registro de los fósiles de vertebrados utilizando la técnicas de estratigrafía secuencia en el sedimento depositados en una cueva con entrada vertical en el paraje de los Tres Charcos de la Provincia de Pedernales

El registro fósil indica que la isla de La Española mantenía una rica diversidad de mamíferos y aves que se han extinguido sólo recientemente (1,2). Se sabe poco, sin embargo, sobre los reptiles que se preservan en los mismos yacimientos. Para probar la hipótesis de que las comunidades de reptiles de La Española también han sufrido declives sustanc...
Article
Full-text available
Insular giant tortoise diversity has been depleted by Late Quaternary extinctions, but the taxonomic status of many extinct populations remains poorly understood due to limited available fossil or subfossil material, hindering our ability to reconstruct Quaternary island biotas and environments. Giant tortoises are absent from current-day insular C...
Conference Paper
Full-text available
There are currently two endemic primate species known from Hispaniola. A large collection of cranial and postcranial specimens of Antillothrix bernensis have been recovered from the eastern and northern Dominican Republic. The second species, Insulacebus toussaintiana, was described from craniodental remains from southwestern Haiti; the sample also...

Project
A multi-institutional collaboration to survey Caribbean biodiversity, principally as represented by faunal remains in the underwater caves of the Dominican Republic. A specific goal is to better understand the paleobiology of Hispaniola primates and the cause and timing of their extinction.
