Are these petrified pinecone I found?

I was searching thru an old box of fossils that I found in my backyard quite a few years ago. As I was washing them off, I noticed a few of them had interesting patterns that looked similar to pinecones. I found the fossils in Eastern Washington State only about 40 miles away from the Ginko National Forest.

The dots on the lower piece might point to Stigmaria, but I'm not sure.

I agree with stigmaria.

Stigmaria seems a bit unlikely to me, given the age of the strata around Ginkgo Petrified Forest State Park (mostly Cenozoic). I am unsure about this specimen (the photographs are quite difficult to interpret), but fossil pine cones are known from Washington state. This specimen, for example, shows circular structures (probably sections through cone bracts).

Thanks for the information, I'll try to put a better photo

Yes, that looks to be a section through a petrified pine cone. Excellent specimen!

Thanks for the verification
