Cretaceous Stage Boundaries

[Hilbrecht@xxxxxxxxxxxx (Heinz Hilbrecht)]

This message goes to the Cretaceous branch among the biostratigraphers.
There was a meeting at Belgium a short time ago where formal definitions of
Cretaceous stage boundaries have been made. Is somebody out there who was
on the meeting (I could not come unfortunately)? ... and took notes I
should say, because a colleague from our institute was there but did not
record what was decided.

My specific questions are for definitions of the Albian/Cenomanian, the
Cenomanian/Turonian, and the Turonian/Coniacian boundary. For the community
it may be worthwile if the other definitions could also be broadcasted
through the Internet. It will probably take a while until the publication
is printed.

Many thanks!

Heinz Hilbrecht
