Stingray (Heliobatis)
Learn More

This year, we are fortunate to be able to offer not only a Guitar Fish from Lebanon, but from the Green River Formation, in Wyoming, this exceptional Stingray mortality specimen, Heliobatis. "Helios, meaning (Sun) and "Batis", meaning (ray). With no more than 2-3% touch up, this specimen would sit nicely in any museum.

The little Knightia fish on the tip of this exceptionally well preserved Ray almost looks as it was skewered by the Ray's caudal fin, barbed tail. And, it is in this position naturally. It was not added. Overall, every detail of this specimen has been painstakingly revealed, giving one a very precise look and understanding of what the skeletal system of these bizarre creatures is comprised of. The fine bones in its "wings" are amazingly detailed as well as the critters spine and the rest of the complete anatomy. This is truly a piece anyone (collector or not) would be proud to display. The slab is already backed with  a wood type substrate. So, a hanging cleat could be easily used for wall display. Or if one wishes, we can include a support stand. 

Overall measurements:~21-3/4" x 13-1/4" x 1" thick

Specimen measurement: ~ 13" x 7"

Location: Green River formation / Split layer, Kemmerer, Wyoming, U.S.A.
