costaricajc Posted April 24 Share Posted April 24 I found this at Rio Picagres (northwest from Rodeo) it looks like a perfect bean seed. that river bed contains quartz and we found a geode once. What do you think about this? Link to comment Share on other sites More sharing options...
M Harvey Posted April 24 Share Posted April 24 That looks like a seed but I don't think it is fossilized. I know nothing about tropical plants. 2 Link to comment Share on other sites More sharing options...
Rockwood Posted April 24 Share Posted April 24 Some seeds can be surprisingly hard. I agree that this looks as if it could be modern. 1 Link to comment Share on other sites More sharing options...
costaricajc Posted April 25 Author Share Posted April 25 it is cold to the touch, it bounces on a tile floor, I am sure it is rock but the level of detail confuses me. I don't want to scratch it or anything I don't know how to test it. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted April 25 Share Posted April 25 I think modern too. Many of the seeds from members of the family Fabaceae are extremely hard. Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...

I don't want to scratch it or anything I don't know how to test it. It takes a bit of technical ability, but if you're up to testing its specific gravity that should do it. 1 Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted April 25 Share Posted April 25 Try a flame. A modern seed will burn and stink. A fossil seed will not be affected. 2 Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
M Harvey Posted April 25 Share Posted April 25 You could try soaking it for a week to see if it sprouts. Would not harm a fossil. 1 1 Link to comment Share on other sites More sharing options...

Coco Posted April 25 Share Posted April 25 Hi, When I went to Reunion Island, we found seeds on the beaches that looked a bit like that. They were terribly hard, but recent !
