[coccoliths] Tribrachiatus acme

[Emma Sheldon]

Hej Jean

I found lots of them in the Ølst Fmn (Early Ypresian) from the Femern Bælt between Denmark and Germany. T. orthostylus is mentioned in the attached article, but I just checked my count sheets and have written ‘lots’ against them in some wells, if that helps!

Best wishes, Emma

Emne: Re: [coccoliths] Tribrachiatus acme

Hi all,

Has anyone ever recorded an acme of Tribrachiatus orthostylus or does anyone know of a published reference to one?

Thanks!
Jean
