xDiamondX Posted January 29, 2018 Share Posted January 29, 2018 I have come across a Keichosaurus from ebay... it does look quite good after trawling across the numerous threads that exist on this forum. Can someone have a second look for me? Thanks Link to comment Share on other sites More sharing options...

xDiamondX Posted January 29, 2018 Author Share Posted January 29, 2018 I think that's because its head is actually embedded inside the stone Link to comment Share on other sites More sharing options...
Kane Posted January 29, 2018 Share Posted January 29, 2018 If a good section of the skull is indeed tucked under the rock, it may be worthwhile to question why such a critical feature would have been left that way when so much detailed preparation work has been done to the rest of the specimen. I would find it odd that this is where the prep effort would suddenly stop. 1 ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Fossildude19 Posted January 29, 2018 Share Posted January 29, 2018 Another possibility could be that they were over aggressive with the wire wheel, and what you are seeing is what is left of the skull. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

aplomado Posted January 29, 2018 Share Posted January 29, 2018 It looks better than most of them to me. I agree with fossildude19, it looks like they may have accidentally ground the skull down too much. It is still relatively attractive imho.

Tidgy's Dad Posted January 29, 2018 Share Posted January 29, 2018 I quite like the look of this one. I'm thinking (over-imaginatively) that the head got boshed, chewed or worn before fossilization. But probably the preppers did it. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

I agree with over aggressive with the grinding wheel. Also it is a ventral prep and not much would be visible but the bottom of the mandibles anyway. They are very fragile and can be ground or blasted away in an instant. I can see an impression of the jaws and even a few teeth. I think no painting on this one as they surely would have started on the skull. A real keichousaurus with good toes, but indeed a bit much grinding overall. 1 Still Life Fossils Link to comment Share on other sites More sharing options...
xDiamondX Posted January 29, 2018 Author Share Posted January 29, 2018 I think this conclusion begs the question... how much is it worth? Link to comment Share on other sites More sharing options...

xDiamondX Posted January 29, 2018 Author Share Posted January 29, 2018 The seller says it is about 17cm long (outstretched) is this way too short for a real one? Or just not fully developed Link to comment Share on other sites More sharing options...

ynot Posted January 30, 2018 Share Posted January 30, 2018 I tend to be a perfectionist, and would prefer a better head But if it makes You happy, and the price is right, go for it.

Crazyhen Posted January 30, 2018 Share Posted January 30, 2018 This Keichousaurus looks genuine to me, with no painting done. The prepping was done in the usual way (i.e. mechanical grinding + acid washing) for hard slab, and thus the bones and head were eroded like this. Note that the slab was broken into several pieces and glued together. At 17cm long, it's a young adult, likely a female. It's not a very good specimen but still better than many others offered for sale in online platform. 2 Link to comment Share on other sites More sharing options...
xDiamondX Posted January 30, 2018 Author Share Posted January 30, 2018 I agree with everyone about the head being disappointing. What do you think of this specimen? Link to comment Share on other sites More sharing options...
Crazyhen Posted January 30, 2018 Share Posted January 30, 2018 This is also a mechanically/acid prepped specimen (so the bones are usually eroded), slab seems to be intact. The head shows more details as it's in a dorsally pressed position. The slab is thin and so it's more prone to be breaking apart during transportation if not properly packaged.

Tidgy's Dad Posted January 30, 2018 Share Posted January 30, 2018 That one looks great. Though i'd check closely to make sure that all the cracks run through the bone when they should , some seem to , but look at them all. 1 Life's Good! Tortoise Friend.

Seguidora-de-Isis Posted January 30, 2018 Share Posted January 30, 2018 There is no doubt that this second is infinitely better than the first ... In this dorsal position it is rarer, and I like it. Typical rock and mechanical preparation of Guizhou, China. Besides, I see veins of calcite running through the specimen in its entirety, and I did not notice anything that might be suspect. I'd buy him. It's a shame that part of the tail is missing, but still this is good-sized and a very respectable specimen in any collection! 1 Is It real, or it's not real, that's the question!
