The hadrosaur, a 25-foot-long, duck-billed plant eater, died and was quickly covered by water and silt. The mix of chemicals in the water and the dinosaur's own body allowed the quick build-up of calcium carbonate, which enveloped and invaded the skin. Essentially, the skin turned to stone, but kept its form and texture, like a freeze-dried glove.

"You slice through the skin," says Manning, "and you can see original cell boundaries that have been locked in the calcium carbonate cement of this remarkable fossil." From the outside, the skin looks segmented into geometric shapes, like the outside of a soccer ball.

I wonder what level of detail can be retained by the calcium carbonate? How fine grained is the fossil?

Why would the skin be segmented into geometric shapes? Is that a function of the fossilization or a growth pattern of the skin itself?

@rosborne979,

I dont have any close -in knowledge of hadrosaur skin but I believe that the geometric patterns they speak of are the segments on the hadrosaur skin.
Calcium carbonate, since it can form as a precipitrate mud, often develops very detailed fossil casts. I have big piles of fossil casts of a kind of fossil called a Pentamerides which is kind of crinoid. These things almost always are cast in CaCO3 mud and have remarkeable detail. I often use chunks of these fossils for students to learn the art of sample prep ao that they can cut em up on rock saws and mount them on mike slides so they can study and draw the internal structures .
