Auspex Posted August 15, 2009 Share Posted August 15, 2009 I haven't been posting new stuff lately, because I haven't had the financial resources to acquire any. This one, however, I could not pass on. The provenance is sketchy (I came by it third-hand), but it is from France, and indications are that it is from the Quercy "fissure fills". Dating it with any confidence may not be possible; with what I have on it right now, it could be anything from Miocene to Holocene. It is, however, fully mineralized, and heavily rimed with travertine. I have it front-and-center in my mini "museum" at the shop, and it stops people in their tracks "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!

The travertine is formed by the deposition of calcium carbonate in lentic waters under warm climates. " Bruno this is amazing Link to comment Share on other sites More sharing options...

Coco Posted August 15, 2009 Share Posted August 15, 2009 Hi, In France, there are several places where sources produce of the travertin. People come to put down objects there (nests, vegetation etc.) and to take back them some weeks later. Then, they are covered with limestone. Scientifically, I do not think that these objects have some value, this has nothing to do with fossils. The only charm of these sources is this capacity to produce so much carbonate.

Coco I have drilled a small hole into the bottom, and there is no original plant material remaining; is has been replaced. A clue, but no proof... My inquiry continues, through the middleman, as to the exact origin of this piece. So far, it is said to have come from the fissures of Quercy, during an excavation. We will see whether this gets me anywhere...

Shamalama Posted August 15, 2009 Share Posted August 15, 2009 The eggs look so perfectly placed, hard to believe they would be fossilized in that position without some creature coming to take a look-see. Very interesting. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers. When a roadcut presents itself, they tend to lurch and weave. To them, the roadcut is a portal, a fragment of a regional story, a proscenium arch that leads their imaginations into the earth and through the surrounding terrain. - John McPheeIf I'm going to drive safely, I can't do geology. - John McPheeCheck out my Blog for more fossils I've found: http://viewsofthemahantango.blogspot.com/ Link to comment Share on other sites More sharing options...

The quercy is a very karstic region. Maybe it is the reason for which sources are more limestones and produce of the travertin.

Auspex Posted August 16, 2009 Author Share Posted August 16, 2009 I have received some more information: it came from a cave near Saint-Remeze, Ardeche. This is an area of de-roofed paleokarst that was last drained of ground water +/- 5.4 MYA (the Mediterranean underwent a drastic lowering then, which profoundly altered the ground water levels in the region). Since travertine is deposited during immersion, the nest could be at least that old (possibly having been constructed during an annual fluctuation in the water table prior to that). Still a load of supposition, but this kind of research is what I enjoy most "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!
