jhw Posted November 2, 2015 Share Posted November 2, 2015 I posted on this one earlier, and just recieved it, so I thought I’d do a follow up. First let me explain the leap of faith comment. I’ve been looking for one of these at a decent price, and have read all the negative possibilities. So here’s the story on this one. Obviously from China originally, but item location on ebay ad said Israel, but actually shipped from Moscow, Russia! Seller had 0 feedback, and this was the only fossil they had listed. The size was quite a bit smaller than others I’ve seen, but at under $200 delivered I went for it. I must say, I’m pleasantly surprised. I see no indication of paint anywhere under the loupe. All bones are 3D and look right. I can see texture in the larger bones. While not dirt cheap, I think I got a good one. Would love to hear what you guys think. Thanks, JW Link to comment Share on other sites More sharing options...
Troodon Posted November 2, 2015 Share Posted November 2, 2015 I think you did well. I like that its not complete, with some flaws and that the bones have depth. Enjoy...... 1 Link to comment Share on other sites More sharing options...
snolly50 Posted November 2, 2015 Share Posted November 2, 2015 I like that it's an amputee with displaced limb bones. It's great that it looks good under magnification. I'm convinced that "painted-on" features can't withstand such scrutiny. From your description and what I can see in the pictures, I would be pleased to own it. 2 Human beings, who are almost unique in having the ability to learn from the experience of others, also are remarkable for their apparent disinclination to do so. - Douglas Adams, Last Chance to See Link to comment Share on other sites More sharing options...

mikeymig Posted November 2, 2015 Share Posted November 2, 2015 I have had a couple of them and I like the thin bands of calcite or quartz running through them. Makes feel better seeing a natural feature like that on the piece. I also think you did good! Mikey 1 Many times I've wondered how much there is to know. led zeppelin Link to comment Share on other sites More sharing options...
jpc Posted November 2, 2015 Share Posted November 2, 2015 Yes, the calcite veins give suggest it is real to me, esp the one that runs through the lower jaw. Link to comment Share on other sites More sharing options...
Stocksdale Posted November 2, 2015 Share Posted November 2, 2015 (edited) Very nice Keichousaurus. I have one that I bought about 10 years ago. I keep thinking of posting it.... One thing I've wondered as I was looking at mine. Why don't we see plant remains or other remains along with the Keishousaurus? also, does anyone have links to scientific papers or information on these particular deposits?

Stocksdale Posted November 2, 2015 Share Posted November 2, 2015 (edited) Sometimes I ask a question without realizing the answer is only a couple clicks away. Here's a recent paper on the location where the Keichousaurus are found. "Drowning of the Triassic Yangtze Platform, South China, By Tectonic Subsidence Into Toxic Deep Waters of An Anoxic Basin" https://www.researchgate.net/publication/276467188_Drowning_of_the_Triassic_Yangtze_Platform_South_China_By_Tectonic_Subsidence_Into_Toxic_Deep_Waters_of_An_Anoxic_Basin Here's "Functional morphology and ontogeny of Keichousaurus hui" http://www.biodiversitylibrary.org/bibliography/5174#/summary The simple answer to my first question is "duh, they are marine reptiles" and also they suddenly got stuck in anoxic conditions. Before this moment, I wrongly thought of them as being in shallow muddy water.

oilshale Posted November 3, 2015 Share Posted November 3, 2015 Yes, the calcite veins give suggest it is real to me, esp the one that runs through the lower jaw. Chinese fossil forgers have learned a lot, they know that calcite veins suggest to collectors the fossil being real. Now they add "real calcite veins" made out of glue and white pigment as a proof. It's still an indication, but better don't rely too much on these veins. Not every vein is real calcite. JW, this Keichousaur is definitely a genuine one and very nice too - congrats!

snolly50 Posted November 3, 2015 Share Posted November 3, 2015 As I posted earlier I like the piece shown above partially because of the defects. I do believe that variance from the "standard" posture is a plus on the side of authenticity. The piece above appears to be missing an entire manus and the adjacent limb bones are displaced. I think that adds mightily to the circumstantial evidence of a genuine fossil. Here is an image of the only Keichousaurus I own. As you can see, its configuration (along with some other poking) bolsters my confidence in the fact it is a natural specimen. 1 Human beings, who are almost unique in having the ability to learn from the experience of others, also are remarkable for their apparent disinclination to do so. - Douglas Adams, Last Chance to See Link to comment Share on other sites More sharing options...
Stocksdale Posted November 3, 2015 Share Posted November 3, 2015 The one in the OP is quite a bit smaller than typical with smaller forearms. Is that the nature of a juvenile form?
