Beef should be aged a few days before cutting. The amount of aging will depend on the amount of fat covering, desired flavor and temperature. Carcasses that have only a thin fat covering should be aged three to five days; those with more fat, five to seven days. Very little tenderization occurs after seven days.
Ask your average paleontologist who is familiar with the phylogeny of vertebrates and they will probably tell you that yes, birds (avians) are dinosaurs.

Amphibians Frogs are members of the zoological class called Amphibia. Amphibians are cold-blooded (or poikilothermic) vertebrate animals. They differ from reptiles in that they lack scales and generally return to water to breed. They are one of three types of Amphibians.Anura, also called Salientia, (frogs and toads), caudate (salamanders and newts) and caecilians (worm-like amphibians). Herps and Herpetology Amphibians together with reptiles make up a larger group called Herps. The study of reptiles and amphibians is called Herpetology.mphibians Frogs are members of the zoological class called Amphibia. Amphibians are cold-blooded (or poikilothermic) vertebrate animals.
