Bank layer accumulation ("turkey pile") is the unique evolutionary technique developed in the Late Cretaceous by the genus Meleagrididae (or more commonly known as the turkey). This bird existed during the Cretaceous in a period of extreme warm temperatures, walking in the footsteps of the dinosaurs. One of the first birds to walk the planet.
At the boundary between the Cretaceous and Tertiary a major extinction event occurred. Reasons for this extinction are still debated, but a majority of geologists agree that it was the result of an impacting space rock (more commonly known as a meteor). Geologist argue that the Chicxulub crater on the Yucatan Peninsula is the strongest evidence for an extraterrestrial impact at the K-T Boundary.
Paleobiologists have argued that the species that survived the impact were burrowing animals. This sound theory was refuted by scientists who found evidence for turkeys in rock units on either side of the K-T boundary. Fossil remains of these turkeys after the Cretaceous show unique signs of a type of above ground burrow generated solely by turkeys. These amazing birds evolved a means of protecting the majority of turkeys through bank layer accumulation. Simply put these turkeys formed massive mounds of turkeys where the outer turkeys took the brunt of the impact for the greater good of turkey survival. This incredible evolutionary wonder is commonly known as the turkey pile.
