PetrifiedDoubleGulp Posted February 9, 2020 Share Posted February 9, 2020 Found this very very strange bone on the banks of Lake Waco. Any ideas? Link to comment Share on other sites More sharing options...
Rockwood Posted February 9, 2020 Share Posted February 9, 2020 Has to be a scapula. I was afraid it may be human, but that didn't check out. 2 Link to comment Share on other sites More sharing options...
PetrifiedDoubleGulp Posted February 9, 2020 Author Share Posted February 9, 2020 Thanks Rockwood, but before I mislead everyone, I should say its dimensions are 3 1/4" x 3 1/2" x 1/2" Link to comment Share on other sites More sharing options...
Creek - Don Posted February 9, 2020 Share Posted February 9, 2020 I think Rockwood maybe right. I don't see any other four legged animals with scapula like that. Link to comment Share on other sites More sharing options...
PetrifiedDoubleGulp Posted February 9, 2020 Author Share Posted February 9, 2020 Thanks! I'm not sure I'm convinced its human, the pivot point doesn't seem correct, and it arches out in very pointy ways, sort of H.R. Giger esque Link to comment Share on other sites More sharing options...
jpc Posted February 9, 2020 Share Posted February 9, 2020 I don't know what that is bt it is not a scapula. Not a mammal scapula, anyway. 1 Link to comment Share on other sites More sharing options...

PetrifiedDoubleGulp Posted February 9, 2020 Author Share Posted February 9, 2020 It's clear that it has a couple of muscle connection points, and a central pivot on the other side, there's patterning fanning out from those 'connective tissue points', but the shape overall is extreme. I looked into the bedrock in the area, and its all either late pleistocene or upper cretaceous, though I'm not sure if it's fully mineralized. It is not super light, but not stone.

Planko Posted February 9, 2020 Share Posted February 9, 2020 I believe it is a fish bone. I have seen similar on Flathead catfish. About that size but a different shape. I believe it might be called a suprascapula. I am just a mere mortal though. 1 Link to comment Share on other sites More sharing options...
PetrifiedDoubleGulp Posted February 9, 2020 Author Share Posted February 9, 2020 Found this on the web, look at the left cheek area, and I start to see how this shape might fit into something like that Link to comment Share on other sites More sharing options...

Rockwood Posted February 9, 2020 Share Posted February 9, 2020 Homologous to a scapular ? Link to comment Share on other sites More sharing options...
jpc Posted February 9, 2020 Share Posted February 9, 2020 I am leaning towards fish as well. Link to comment Share on other sites More sharing options...
Rockwood Posted February 9, 2020 Share Posted February 9, 2020 I'll lean too. It's a big one. Link to comment Share on other sites More sharing options...

PetrifiedDoubleGulp Posted February 9, 2020 Author Share Posted February 9, 2020 Mawsoniidae? Link to comment Share on other sites More sharing options...
Fossildude19 Posted February 10, 2020 Share Posted February 10, 2020 I don't know that Mawsonia is found there. You should look up what fish fossils are found in the area. I'm guessing Cretaceous in age? Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Creek - Don Posted February 10, 2020 Share Posted February 10, 2020 Couple of cretaceous fish that used to roam around this area was 90 million year old fish called Pentanogmius fritschi which were 5 ft 5 inches long and used to live in Western Interior Seaway and the second one that was displayed at the Perot museum. Forgot the name though. These two are displayed at Perot museum in Dallas, Texas. Link to comment Share on other sites More sharing options...
