Hunting Sea Urchins In French Alpes


Dromiopsis

Recommended Posts

Last sunday, My daughter asked me to go close to a cavern where we can find Toxaster retusus at "Thorens les Glières" in the "haute savoie", close to geneva and Chamonix.

It's sea urchins from lower Cretaceous(Hauterivian), 125 millions years old.

the site(you can remark the "limestones in round loaves of bread"...don't know the exact translation...sorry

fossils in place

after cleaning

and how this sea urchins was living...in the sediments as a lot of irregular sea urchins now.

This site is down of the famous "Plateau des glières", famous area where hundrents of men resisted during the second world war.

Most of the snow, ice, accumulating during winter in the plateau is flushed into galleries and finish by this natural exurgence .30 years ago, a young hydrospeleologue from Normandie passed away in this area,stucked in a siphon during a flood....

There's not so much diversity in this area...oysters(Exogyra couloni)and many shells(Pholadomya).

For people close to this area, the site is called "Grotte de la Diau"

Only 35 mn to climb, no real danger, only 250 meters denivelation.

be careful in spring, iceblocks are falling ....!
