Mike_363 posted a topic in Fossil IDThese two rocks were found in East Texas, mostly Eocene. Property is on Carrizo-Wilcox aquifer. Dry land in wooded area. I've read some about how hematite is formed so I guess this is normal to see a shell and what I think is matrix? Is the shell a print or a shell? Idea of age? Then there's the tubes in the second rock. Is that what those are? Thanks so much for any help.
I_gotta_rock posted a fossil in *Pseudofossils ( Inorganic objects , markings, or impressions that resemble fossils.)Limonite is a type of iron-rich mineral found in igneous formations. It was once used as a source of iron ore and in Delaware was mined for the purpose for two centuries. Limonite tends to form with vugs of easily-weathered minerals, including druse quartz, which leave behind gaping holes and slots. It is easy to picture skulls and other bones in these rocks, whether freshly fractured or stream-worn. This one always reminded me of a dragon skull.
Mathewhepplewhite posted a topic in Fossil IDI have found a large amount of rocks that are strongly attracted to my neodymium magnets. Could this be from iron ore in the rock or does it mean it is a meteor?
