Great video! But in answer, do check out the video below. These videos side by side should get you up to speed!

P.S. This goes really well with the last post with the same labels at:

DNA in turtles that “could challenge tradition hypothesis…as extremely unlikely..”

Peace to the humble!

Update 10/2024: In a study from 04/2023 concerning the above videos and Iron.

“Similarly, results from our iron trial revealed that though iron enrichment in groundwater may facilitate early-diagenetic precipitation of ‘protective’ iron-hydroxide and/or iron-oxide cements/linings, these precipitates alone cannot prevent the dissolution of bone and decay of its biomolecules under highly-acidic diagenetic conditions.”

” These findings suggest that approximately twice as much collagen was lost to decay in the iron trial than in the water control and calcium carbonate trials, and that the femur in the phosphate trial lost ~30% more collagen than the femora in those same two trials.”

Great point that the dinosaur tissue found at many different rock layers/ages are all the same, looking as if they are from the same age! If true, this is an interesting point.
