New Members Cacti123 Posted May 24, 2023 New Members Share Posted May 24, 2023 Found in central Washington in the hills near Mt Adams. Is this a fossilized egg? Link to comment Share on other sites More sharing options...
doushantuo Posted May 24, 2023 Share Posted May 24, 2023 While it's certainly ovoid,I doubt it's origin as the biomineralized end result of vertebrate reproductive behaviour. Link to comment Share on other sites More sharing options...
Ludwigia Posted May 24, 2023 Share Posted May 24, 2023 Probably a concretion, but we'd need more close up photos from different angles to tell for sure. I've never been to Mt. Adams, but a google search has shown me that it's in the middle of a volcanic field, so most of the rocks in the area must be igneous rather than sedimentary. 2 Greetings from the Lake of Constance.

Tidgy's Dad Posted May 24, 2023 Share Posted May 24, 2023 Looks like a limestone concretion to me, but hard to tell from one photo. Not an egg. 2 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
