This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology. People could have hunted Madagascar’s megafauna to extinction, particularly when introduced taxa and drought exacerbated the effects of predation. However, such explanations are difficult to test due to the scarcity of individual sites with unambiguous traces of humans, introduced taxa, and endemic megaherbivores. We excavated three coastal ponds in arid...

Natural vs. Human-caused Extinctions of Terrestrial Vertebrates in the Bahamas (2016)
We report 83 taxa of vertebrates (11 reptiles, 63 birds, 9 mammals) from late Pleistocene bone deposits in Sawmill Sink, Abaco, The Bahamas. These bones were recovered by scuba divers in non-cultural contexts at water depths of 27-35 m. Among the 83 species, 40 (48%) no longer occur on Abaco (4 reptiles, 31 birds, 5 mammals). We estimate that 17 of the 40 losses (all of them birds) are linked to changes during the Pleistocene-Holocene Transition (~15 to 9 ka) in climate (becoming more warm and...
Preliminary Analysis of Extinct Box Turtle Remains from the Late Pleistocene of the Southern High Plains (2016)
A diverse and abundant latest Pleistocene vertebrate fauna is currently being investigated at Macy Locality 100 on the southeastern edge of the Southern High Plains, Texas. Remains of an extinct box turtle (Terrapene carolina putnami) are common among the recovered material from the site's alluvial deposits. Believed to have been a mesic form, the extirpation of the eastern species from the region and the extinction of the T. c. putnami are ostensibly linked to ecological changes of the terminal...
