Over at my page "Jawless Fish From The Lower Devonian Lost Burro Formation, Death Valley National Park, California" at Jawless Fish From The Lower Devonian Lost Burro Formation, Death Valley National Park, California --a subsection of my primary site "Fossils In Death Valley National Park"--I've uploaded images of fossil specimens of the world-famous pteraspidid jawless fish (Panamintaspis snowi and Blieckaspis priscillae) professional paleontologists have collected (with full formal approval from the National Park Service, naturally) from the lower Devonian Lippincott Member of the lower to upper Devonian Lost Burro Formation at Trail Canyon, Death Valley National Park. The fossil fish are therefore roughly 405 to 390 million years old.
Admittedly, of course, the vertebrate remains appear less than visually spectacular--they're obviously not what most folks would immediately recognize as fossil fish material. But they're paleontologically priceless finds, indeed, providing much additional information on the anatomy, lifestyle, and paleo-habitats of such early jawless fish.
Also included at my page are two scientific reconstructions of the Devonian fish heads.
The entire original, scientific technical paper from which the images came can be downloaded free of charge, in pdf format, from Researchgate over at Researchgate PDF Document Access .
Before I recently obtained the scientific paper, I'd hiked Death Valley's Trail Canyon several times, with camera in hand, trying to locate the paleontologically renowned jawless fish in the lower Devonian Lippincott Member of the lower to upper Devonian Lost Burro Formation--with zero success. Now that I know exactly what to look for, my next expedition could well prove photographically productive.
