My name is James St. John. I'm a geologist and paleontologist at Ohio State University, Newark campus.

My real e-mail is "stjohn.2" at "" - I don't use the Yahoo-imposed e-mail address, so don't send messages to it.

Because flickr deleted easy access to photo collections in early June 2017, here is the link:

All of the geology & biology photos and write-ups here are intended for educational purposes. Photos and write-ups may be used by anyone, anywhere, for any purpose (except creationism or other pseudoscientific nonsense), for free, forever. I know of at least two instances of creationists using my photos to push their ridiculous woo-woo.

You don't have to ask me for permission to use stuff, but it would be nice if you'd let me know about it, if possible. Please don't purposefully misrepresent any of these photos or videos (that includes putting your own copyright on them if you post them elsewhere - I don't claim anything on these, but no one else can either; this also includes putting digital watermarks on my photos if you post them elsewhere - don't do that). Reasoned corrections or clarifications are welcome. Unfounded assertions are not welcome - please provide evidence.

All write-ups are my syntheses from the geologic literature and/or personal experiences and observations. Non-personally obtained info. comes from references that are cited in many of my photo captions, but not all of them. It hasn't been feasible to always keep track of the hundreds and hundreds of specific references from which info. is derived. Simple searches of the geologic literature (e.g., use GeoRef) will provide most of the same references I used.
