aplomado Posted April 13, 2016 Share Posted April 13, 2016 I recently found a short little webpage with a picture of what is claimed to be an opalized dinosaur skull, a Kakuru dinosaur. . I have no idea if it is real, though I know some fossils are opalized. Anyone familiar with this specimen? I haven't found a better picture. http://athosdinos.blogspot.com/2013/10/kakuru-kujani.html Link to comment Share on other sites More sharing options...
sseth Posted April 13, 2016 Share Posted April 13, 2016 While their have been opalized skulls found (like Eric the Plesiosaur http://io9.gizmodo.com/5987941/eric-the-pliosaur-one-of-the-most-interesting-fossils-on-the-planet) this is not one of them. the anatomy is all wrong and it simply looks like a creation of Photoshop. 1 _____________________________________ Seth www.fossilshack.com www.americanfossil.com www.fishdig.com Link to comment Share on other sites More sharing options...
Troodon Posted April 13, 2016 Share Posted April 13, 2016 Agreed it looks like it's fabricated. Wikipedia who is a reference I do not like to use states that this species is only known from a few leg bones and the tibia was opalized? 1 Link to comment Share on other sites More sharing options...

FossilDudeCO Posted April 13, 2016 Share Posted April 13, 2016 ^ is there anything faker than fake? As for opalization though. I have never seen it myself in bone. Do these specimens (which I assume are rarer than rare) tend to opaline all the way through? Or just on the outer layers? Link to comment Share on other sites More sharing options...
Auspex Posted April 13, 2016 Share Posted April 13, 2016 ...Do these specimens (which I assume are rarer than rare) tend to opaline all the way through? Or just on the outer layers? The Australian plesiosaur is described as being " opal-covered". 3 "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!

ynot Posted April 13, 2016 Share Posted April 13, 2016 Do these specimens (which I assume are rarer than rare) tend to opaline all the way through? Or just on the outer layers? Opal fills voids in the rock / bone where it is found. The bone would have to dissolve out and would then have the hole filled with the opal for the opal to be a complete replacement of the bone. I have never heard of this. But I have seen shells like that. Tony 1 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

The Amateur Paleontologist Posted May 2, 2016 Share Posted May 2, 2016 It's definitely a fake. The anatomy is totally wrong, and it clearly doesn't belong to an animal that was similar to Kakuru kujani. If it was real, a fossil like that would be as famous as Eric the pliosaur. The only remains of Nakuru were a partial opalised tarsometatarsus and a possible pedal phalanx. 1 Opalised fossils are the best: a wonderful mix between paleontology and mineralogy! Q.

Arion Posted May 2, 2016 Share Posted May 2, 2016 Looks like a poorly-modelled Ornitholestes skull in which the infratemporal fenestra has mysteriously disappeared. Link to comment Share on other sites More sharing options...

The skull of the Ornitholestes holotype has an infratemporal fenestra (see drawing of Ornitholestes holotype skull at Wikimedia). Only thing is, a clear view of the infratemporal fenestra in AMNH 619 is complicated by the braincase inside the skull. Link to comment Share on other sites More sharing options...

Yes, that was my point; Ornitholestes (like every other dinosaur) has an infratemporal fenestra. The absence of one in the OP’s “skull” is a glaring inaccuracy indicative of forgery by someone who doesn’t really understand tetrapod anatomy. 2 Link to comment Share on other sites More sharing options...
JohnJ Posted July 25, 2020 Share Posted July 25, 2020 I realize this topic is over four years old, but the "opal" in this image looks Photoshopped.
