Esconichthys apopryis from the upper carboniferous (325 million years) of the Mazon Creek formation, Braidwood, IL. This diminutive lungfish is about 1/2 grown.

Phareodus encaustis is an osteoglossid (arowana) that comes from the Eocene of the Green River Basin formation in Wyoming. I've also attached a jaw from a larger specimen than the one photographed (really wish I'd found the complete fish)

Here's another Osteoglossid (arowana) called Phareodus testis. Climate changes killed off the 2 known US-native aro species. Darn the bad luck. This one is also from the Eocene (50 MYO) Green River Basin formations of Kemmerer, Wyoming.

This codlet is still not identified. But, because of the filaments, it looks just like the paradise threadfin. From the Eocene of southern France.
