Currently I'm working on many hadrosaurs with skin from Mexico.
At least 50% have skin preserved. All the skin is preserved as
impressions. Most of our diverse hadrosaurs are in brackish water
deposits. Several have oysters encrusting the skin impressions. To
preserve skin in water so that oysters have time to grow on it is tough
to imagine. I believe it drys to rawhide first, but I doubt it was very
thin to do this. I would guess about as thick as an elephants at least.
No skin I know of is preserved such that thickness can be measured
directly. The wrinkling is from drying and thickness would decrease
during that process such that some tight folds may be possible. We
observe this also. I wish S. Czerkas would publish some of his views and

I applaud him for that.
