Question & self-introduction

[Attila Fogarasi <fogarasi@xxxxxxxxxxxxxx>]

Dear Netters,

I used to read paleonet, however this is the first message I post, so I think,
I should shortly introduce myself. I am a PhD student at Eotvos University,
Budapest, Hungary. I study Early Cretaceous calcareous nannofossils of some
Hungarian outcrops. There are some serious problems in biostratigraphy, since
ammonites, foraminifers and nannoplankton gave different ages. I would like to
reevaluate nannofossil studies in my PhD. 

My question concerns foraminifera. There are some "Albian" forms described:
  Spirillina mediogranulata Riesch
  Praeglobotruncana cf. delrioensis Plummer
  Pseudoclavulina gaultina Moroz.
  Osangularia cf. brotzeni (Gand.)
  Eoguttulina anglica Cush. & Ozaw.

Could you give me some new reference concerning the age of these forms? How
significant are the first occurence of these taxa? 

Thank you,

Attila Fogarasi
