Wow, this would be exciting.
It would be nice (and remarkable in the extreme) if functioning gametes (sperm cells in the case of this article) could be found. I'm wondering if it wouldn't be worthwhile to look also for female gametes (eggs) and do in vitro fertilization of a bunch, and implant 'em in a modern elephant mama as the host. And of course, do it more than once. But there's been such a project going (looking for sperm) for around ten years, and the idea has been around for at least 30 I think. So far, bupkis.
