These are photographs courtesy an individual who goes by the cyber-name coolislandsong24; the fossil specimens presently reside in the following museum vertebrate paleontological repositories--Raymond Alf Museum of Paleontology; and the San Bernardino County Museum.

A lower jaw from a saber-tooth cat, Upper Member of the middle Miocene Barstow Formation, Fossil Bone Basin, Mojave Desert, California. Called scientifically, genus Nimravides. 13.6 to 13.4 million years old. A specimen that presently resides in the San Bernardino County Museum. Photograph courtesy an individual who goes by the cyber-name coolislandsong24. I edited and processed the photo through photoshop.

Camel articulated foot bones, Upper Member of the middle Miocene Barstow Formation, Fossil Bone Basin, Mojave Desert, California. 15 to 13.4 million years old. Two proximal phalanges (toe bones), connected to the distal portion of the metapodial (which in turn articulates, higher up, with the tibia--the lower leg bone--not shown in this photograph). A specimen that presently resides in the Raymond Alf Museum of Paleongology. Photograph courtesy an individual who goes by the cyber-name coolislandsong24. I edited and processed the photo through photoshop.

Horse articulated limb bones, Upper Member of the middle Miocene Barstow Formation, Fossil Bone Basin, Mojave Desert, California. 15 to 13.4 million years old. A view of all the bones in a horse hock (including astragalus, calcaneus, and tarsals), in their natural articulated relationship with the metapodial (long lower foot bone, at right) and a fragment of the distal portion of the tibia (lower limb bone, at left). A specimen that presently resides in the Raymond Alf Museum of Paleongology. Photograph courtesy an individual who goes by the cyber-name coolislandsong24. I edited and processed the photo through photoshop.

A pecarry skull, with upper jaw palate preserved, Upper Member of the middle Miocene Barstow Formation, Fossil Bone Basin, Mojave Desert, California. 15 to 13.4 million years old. A specimen that presently resides in the Raymond Alf Museum of Paleongology. Photograph courtesy an individual who goes by the cyber-name coolislandsong24.
