This is an incredibly diverse collection of ice age micro fossils from 10 different species. Included are: A mole ulna, an alligator tooth, a vole molar, a pike fish tooth, a salamander vertebra, a bat jaw, a snake vertebra, a musk turtle jaw, a frog vertebra, and a green anole (lizard) jaw. Incredibly detailed set of micro fossils. Pictures do these absolutely no justice.
