Abstract

Dinosaur eggshell and evidence for wildfires are common in the fossil record. The effects of fire on ostrich and emu eggshell, modern analogs for dinosaur eggshell, were examined by burning fragments in flames of two different temperature ranges for a series of time intervals. Percent mass loss increased directly with both time and temperature. Different treatment conditions also displayed regular patterns of change in color and curvature. Exposure of eggshell to flame results in dramatic physical changes, knowlegde of which could be useful to paleontologists studying dinosaur nesting ecology.
