    "Surely not, he must be sorely mistaken!" I hear you ask!

    That the ammonites died out 65 million years ago at the end of the Maastrichtian of the Cretaceous has never seriously been questioned. Now it appears that a few species Hoploscaphites actually soldiered on and survived into the Danian of the Paleocene in central Europe.

    A new paper reveals in detail this astounding discovery:

    The paper is exceptionally detailed; if it appears too much in one go, try tackling just the Abstract and Summary.

    I haven't read it yet, but I can't wait to. It wouldn't be the first time someone mistook reworked specimens, but I'll wait to read it to pass judgement.

    200,000 years after the K-T (or K-Pg) boundary, an isolated population survived in the seas around Denmark. I guess it's possible. :shock:

    Have to wait for this paper:
    Machalski, M. and Heinberg, C. (in press). Evidence for ammonite survival
    into the Danian (Paleogene) from the Cerithium Limestone at Stevns
    Klint, Denmark. Bulletin of the Geological Society of Denmark 52.


    Anyone have access?

    Thanks Phil !!! That made my day :grin:

    I should have read a little closer, seems there are Scaphitids and Baculitids in a couple of areas :oops:

    why not indeed ? too much is often assumed from scant little evidence by us humans, long live the ammonites !
