Real Keichosaurus?

[xDiamondX]

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

Head looks kinda funny, but the rest looks alright to Me.

[xDiamondX]

I think that's because its head is actually embedded inside the stone

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.

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.

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.

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.

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.

I think this conclusion begs the question... how much is it worth?

Sorry, but the Fossil Forum does not do appraisals.

The value of a fossil is greatly dependent on things that can not be determined from a picture.

I got a bit excited there, sorry

 

I'll leave it at that

The seller says it is about 17cm long (outstretched) is this way too short for a real one? Or just not fully developed

They all started as really small babies.

[xDiamondX]

ynot, do you think this would be a respectable specimen?

[ynot]

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]

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.

[xDiamondX]

I agree with everyone about the head being disappointing. What do you think of this specimen?

 

 

[Crazyhen]

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.

[ynot]

Looks much better than the other one.

[steelhead9]

Better than the first. 

[Tidgy's Dad]

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.

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!

This looks like a "her" to me.  The humerus of female tends to be more slender and shorter than that of male, with unpronounced ends both proximally and distally.

[xDiamondX]

@CrazyhenDoes the tail on the female look cut off? or it just ends right on the edge of the plate?
