The first blog hopes to introduce the principles of #micropalaeontology and how it has deep roots in the disciplin of #biostratigraphy. However micropalaeo also has many other applications, particularly in the field of palaeoenvironmental reconstruction.

Etheldred Benett: The Fossil Hunter Who Read the Earth in Secret She whispered to the earth, and it answered in stone. Forgotten for a century, England’s first female geologist finally speaks. Witness the resurrection of a lost legacy, uncovering the hidden stra…

Ammonite Biostratigraphy of the Cretaceous—An Overview An ammonite zonation of the Cretaceous period is presented, which largely follows the Geological Time Scale 2012, with illustrations of several index species. Concepts of Cretaceous ammonite biostratigraphy are briefly discussed and characteristic examples of the...

Ammonoid Biostratigraphy in the Jurassic In the Jurassic, ammonoids showed the most rapid evolution and thus are successfully used as tools for subdividing and dating marine sediments of this period. Evolutionary driven morphological shifts ...

Ammonites from the latest Aalenian–earliest Bathonian of La Baume (Castellane area, SE France): palaeontology and biostratigraphy - Swiss Journal of Geosciences Middle Jurassic strata are naturally exposed around the village called La Baume, near Castellane (Alpes de Haute Provence, SE France). We have realized both a detailed log and a bed-by-bed sampling fo...

#BlastFromThePast My 1st publication concerned my Msc

Taking a chance and turning to the scientific community on Bluesky for help.
I am looking for someone with good knowledge of the taxonomy and phylogeny of Graptolites, to help datation of Ordovician strata.

A few specimens found in strata some 450MY old by my colleague. We are trying to refine the geological chronology of the area, in connexion with current work on the Charlevoix Astrobleme.
