| Comment: | This rare species was known previously only from the western Beaufort Sea in depths of 585 to 2,195 meters. The species has no record as a fossil and the genus is cited in the literature as “Recent and possibly Pliocene,” though without any reliable basis for the “Pliocene” age call. Many “Pliocene” age calls for Arctic invertebrates done in past years have turned out to be Pleistocene using more modern criteria. The small chunk of matrix that contained this mollusk appears to be diatomaceous, and fragments of what look like ostracods are common too. It would be very worthwhile to submit this matrix, or more like it, to John Barron (P$S, Menlo Park) for diatom analysis and/or to Elisabeth Brouwers (P&S, Denver) for ostracode analysis; preferably, you have enough matrix to give them both a chance at age-dating your sample. Because the one specimen of AXINULUS CAREYI is articulated and closed, and shows no signs of abrasion, it presumably was deposited in situ and not transported after death, and it is also very unlikely that it has been reworked from an older deposit. |
