Recent Developments in the Analysis of the Black Mat Layer and Cosmic Impact at 12.8 ka Bibs and Bios: William C. Mahaney, Leslie Keiser, David H. Krinsley, Allen West!, Randy Dirszowsky, Chris C.R.

In a recent interview with NBC News anti-YDB jihadi Nick Pinter claimed that “the pro-impact literature is, at this point, fringe science being promoted by a single journal.”
This is nonsense — and easily disproven. The critics of the YDB hypothesis have published 10 times in PNAS (see […]

Abstract: Previous work has ascribed a cosmic impact origin to black, high-temperature, carbon-encrusted beds (2–3 cm thick), associated with the Younger Dryas readvance of ice at 12.8 ka during the Late Glacial in the northern Andes of Venezuela. The […]
The breakup in space of a comet or asteroid prior to impact could produce a surface or oceanic impact by the largest object, and hundreds of smaller fragments could create air-bursts affecting an entire hemisphere (Bunch et al. 2012). Approximately 90% of all ejecta from the main impact would fall within five crater radii, although […]
Distinguished Science writer Dr. Richard Kerr walked the plank this afternoon in response to this morning’s Knight Science Journalism Tracker inquiry of science writers.
Charles Petit’s casual post brought quick attention from the old-school dean of science writing. Kerr implored his press colleagues to, in effect: Move on, move on…There is nothing […]
The PNAS paper has a helpful bibliography of recent publications supportive of the hypothesis. It’s worth a separate block quote below.
Nice how the links take you to the cites themselves at the PNAS website.
“Some independent workers have been unable to reproduce earlier YDB results for MSp, CSp, and NDs […]
At the end of the Pleistocene a Younger Dryas black mat was deposited on top of the Pleistocene sediments in many parts of North America. A study of the magnetic fraction (~10,900±50 B.P.) from the basal section of the black mat at Murray Springs, AZ revealed the […]
Skeptics of the YDIB hypothesis frequently state that “no one can reproduce the YDIB results” (Kerr, 2010); “nobody has found anything” (Kerr, 2010); there is a “lack of reproducibility of data” (Holliday, 2011); and “unique peaks in concentrations at the YD onset have yet to be reproduced” Pinter (2011). These casual dismissals […]
An international team of scientists representing a number of disciplines locate bizarre materials and ET impact markers in a distinct layer of well-dated sediments from the initiation of the Younger Dryas and publish their findings in a major scientific journal. 2007 Firestone et.al. in PNAS?
Nope. W.C. Mahaney et. al. Geomorphology — March 2010.
