Sternum of bird.

Sternum of bird preserved as three-dimensional imprint in diatomite

Part and counterpart of sternum (breastbone) preserved as imprint of both upper and lower face. The imprint is relatively complete, and will quite likely be determinable to family level.

The shape of the sternum, with long, paired sidebars, where the outer one has a marked "foot" is similar to the sternum of modern Trogons (Order Trogoniformes) or the closely related Rollers and Kingfishers (Order Coraciiformes).

In recent times, trogons are limited to the tropics, with several species in Middle and South America, and a few species in Asia and Africa south of the Sahara. Only a few fossil species are known from the Palaeogene. Rollers and Kingfishers have a wide distribution today, which it appears they also had during the Palaeogene, even though the number of described fossil forms are limited.
