Here it likely means a different geological stratum than implied by
the exhibit label. That difference may either relate to age and/or
location (or both) of said layer of rock.

I'd say start here, https://en.wikipedia.org/wiki/Nyctosaurus , and
then ply http://scholar.google.com/ . I'd say it's noteworthy that
