I found a spot with a lot of petrified things in it. they look really cool but not sure if they're worth anything or exactly what they are need help. in the smaller rock there are spots like I've never seen before really curious looks really cool

looks like fossiliferous chert

Yup, probably chalcedony. If you want to be sure, quartz will scratch opal. (a hardness test will tell)

Yep. Microcrystalline quartz. Nice specimen.

If you want to know the sea critters' names, pop over to the fossil forum, or ask locally. Whether they are worth the time, I'd say a definite yes, it would be fun to find a variety of different fossils, find more voids that have chalcedony/quartz in them, maybe crystals in some?? What a fun find!
