PHASIANUS CHOLCHICUS

Common Pheasant, Phasianus Cholchicus
These playful lovelies are beautiful examples of the Common Pheasant, Phasianus Cholchicus. We associate them with tweet shorn English aristocrats jauntily going about the hunt on horseback. Pheasants build their nests on the ground and can fly for short distances. They spend their days searching around field and stream looking for tasty insects, seeds and grain.

PUMA CONCOLOR

Cougars are meat-eating mammals (primarily dining on deer) who boast being the most widely distributed land mammal in the Western Hemisphere. They are impressive athletes, able to leap 18 feet or more straight upward from a sitting position.

They lead solitary lives and are excellent at avoiding humans for the most part. Cougars have a massive range which runs from the mountainous Canadian Rockies in northwestern Canada all the way down to Patagonia in South America. These cats make their dens in mountain graggs, along rocky ledges, in dense woodland areas and under uprooted trees and debris.

HOLCOPHYLLOCERAS

Amazing suturing on this lovely ammonite, Holcophylloceras mediterraneum, (Neumayr 1871) from Late Jurassic (Oxfordian) deposits near Sokoja, Madagasgar.

The shells had many chambers divided by walls called septa. The chambers were connected by a tube called a siphuncle which allowed for the control of buoyancy with the hollow inner chambers of the shell acting as air tanks to help them float.

We can see the edges of this specimen's shell where it would have continued out to the last chamber, the body-chamber, where the ammonite lived. Picture a squid or octopus, now add a shell and a ton of water. That's him!
