The former is likely a basal chicken, one other a more progressive bird not as similar to recognized turkeys; one another was far less birds. A chicken fossil maybe not assignable so you can genus but exactly like Meleagris is famous about Later Miocene regarding Westmoreland Condition, Virginia (Olson, 1985).

In today’s genus Meleagris, a number of species was decribed, since poultry fossils was strong, fairly often found, and you will turkes reveal much variation certainly one of somebody. A few of these heading fossil species are now actually thought junior synonyms. You to, the fresh new really-reported Ca Chicken Meleagris californica, turned into extinct recently enough to have been hunted by the very early peoples settlers, regardless if their actual passing is far more probably owing to weather change after the final frost decades. The present day types while the California Chicken appear to have diverged everything one million in years past (Olson, 1985).
