The eggs and overall nest construction closely resemble the eggs and pods of modern grasshopper species.
Insect eggs are extremely rare in the fossil record, and intact egg cases are even rarer.
This wasn’t just a cluster of eggs — it was a type of subterranean egg pod called an ootheca, with the eggs cradled by a protective layer that had mineralized into a stony rind.
So Lee consulted a global insect egg database, containing more than 6,700 living species, to identify the eggs in the fossil pod.
The virtually pristine specimen also speaks to the level of preservation in the national park site’s fossil beds, Famoso added.
