Summary
| Description |
English:
Proposed soft tissue preservational pathway based on examination of NDGS 2000 (
Edmontosaurus
sp.).
(A) Incomplete predation and/or scavenging of the carcass creates openings in the body wall through which fluids and gasses can escape. (B) Invertebrates and microbes use those openings to access the internal tissues. (C) Removal of internal soft tissues and drainage of fluids and gasses associated with decomposition allows the deflated skin and other dermal tissues to desiccate and drape over the underlying bones. This process facilitates longer-term persistence of the skin and other resistant soft tissues until eventual burial and fossilization. Paleoart by Becky Barnes.
