The STRATOTYPES (by Mrs Ruault-Djerrab)

This video quickly presents the notion of stratotype, which in fact corresponds to a standard section or reference section, which is used to define a geological stage or the limits of a stage. It is internationally recognized and defined according to precise criteria. The name of the original stratotype is used to define the name of the stage.
This video has been put online for beginners in geology, in particular in License 1 and 2 at the University, or for high school students in science courses.
Video highlights:
- 0:07: Introduction
- 0:40: Importance and characteristics of stratotypes
- 2:44: Where are the stratotypes?

Madame svp est ce que vous pouvez faire des vidéos concernant le cours de paléontologie (non pas le tp Pcq j'ai vu que c'est déjà posté)
Merci pour vos efforts

[@tpgeologie]

On verra peut-être dans le futur... Mais il me semble que c'est plus utile pour les tp car vous pouvez observez des échantillons ce qui est très important.
Si vous le souhaitez, vous pouvez retrouver mes cours sur mon site internet, par exemple à cette page pour le cours de paléontologie :
