Mr. Verano said the children's skeletons contained lesions on their breastbones, which were probably made by a ceremonial knife.

Unlike other birds, their "flat breastbones lack the keel that anchors the strong pectoral muscles required for flight," says National Geographic.

He had a broken neck, a punctured lung, 15 broken ribs, fractures in both breastbones and multiple breaks in his right leg.

In 1810, his skeleton was added to the Museum Anatomicum in Marburg. His skeleton is not complete: one arm is missing, his shoulder blades are not connected, his breastbones are missing, and his feet are made of cork.

Pengornithids were primitive enantiornithes. They had many small teeth in their jaws, and stout legs. Their internal anatomy was characterized by a hooked outgrowth of the shoulder blade and a pygostyle (the tail bone to which long feathers attach) which was short and rounded, instead of long and blade-shaped as in other enantiornithes. While most enantiornithes had four long backward projections growing from their breastbones, pengornithids only had two.

However, in many analyses, this definition would be synonymous with the more widely used name Ornithurae. An alternate definition was provided in 2001, naming Carinatae an apomorphy-based clade defined by the presence of a keeled sternum. The most primitive known bird relative with a keeled breastbone is Confuciusornis. While some specimens of this stem-bird have flat breastbones, some show a small ridge that could have supported a cartilaginous keel.

Yarrell states that Fussell drew "nearly five hundred" of the 520 wood-engravings mentioned on the book's title-page. The work began in 1837 and continued for six years, Yarrell publishing at the rate of one instalment, containing three sheets, every two months. Many of the drawings were from skins or stuffed specimens, though every bird species is illustrated with a lifelike drawing of the bird standing (or rarely, flying or swimming) in a natural setting. Additional drawings depict nests, feathers, and details of bird anatomy including feet, breastbones, and windpipes.

Additional drawings depict nests, feathers, and details of bird anatomy including feet, breastbones, and windpipes. Simon Holloway suggests that Fussell and the engravers Charles Thompson and sons probably made all the illustrations for the first three editions of Yarrell's Birds. Only in the fourth, rewritten edition of 1871–85 were illustrations by other artists (Charles Whymper, J. G. Keulemans, Edward Neale) added.

Much of the meat was salted in barrels for storage, but the rest of the bird was also used. Islanders paid their rent in feathers for stuffing pillows and furniture, the gannet stomachs were used to hold oil derived from the carcasses, and the breastbones served as lamp wicks. Hunting on St. Kilda ceased in 1910, but the gannetry on Sula Sgeir is still exploited under a licence that permits 2,200 chicks to be taken each year. During the hunt, 10 men live on the island, and the cleaned birds are singed on a fire fuelled by their own oil-rich offal.

Janensch based his description of B. brancai on "Skelett S" (skeleton S) from Tendaguru, but later realized that it comprised two partial individuals: S I and S II. He at first did not designate them as a syntype series, but in 1935 made S I (presently MB.R.2180) the lectotype. Taylor in 2009, unaware of this action, proposed the larger and more complete S II (MB.R.2181) as the lectotype. It includes, among other bones, several dorsal vertebrae, the left scapula, both coracoids, both sternals (breastbones), both humeri, both ulnae and radii (lower arm bones), a right hand, a partial left hand, both pubes (a hip bone) and the right femur, tibia and fibula (shank bones).

The pen for the remaining drawings, if any (the title page asserts there are 520 in the book), is not stated. As well as the figures of birds, there are 59 tail-pieces (following Bewick, small woodcuts to fill in the spaces at ends of articles), of which some are whimsical, like Bewick's, but many illustrate anatomical details, especially breastbones and windpipes, and others, although decorative, realistically depict aspects of bird behaviour or human interaction with birds. For example, the tail-piece for the "Jack Snipe" shows a bittern among reeds, swallowing a frog, while that for the "Common Bittern" shows "a mode of shooting an Eagle from a pit". Fussell's work began in 1837 and continued for six years.

Fossilized eggs of Gobipteryx minuta, Dinosaurium (Prague) Known enantiornithean fossils include eggs, embryos, and hatchlings. An enantiornithean embryo, still curled in its egg, has been reported from the Yixian Formation. Juvenile specimens can be identified by a combination of factors: rough texture of their bone tips indicating portions which were still made of cartilage at the time of death, relatively small breastbones, large skulls and eyes, and bones which had not yet fused to one another. Some hatchling specimens have been given formal names, including "Liaoxiornis delicatus"; however, Luis Chiappe and colleagues considered the practice of naming new species based on juveniles detrimental to the study of enantiornitheans, because it is nearly impossible to determine which adult species a given juvenile specimen belongs to, making any species with a hatchling holotype a nomen dubium.

According to the researchers' notes in the study, there was cut marks on the sterna, or breastbones some of the children and the llamas. Children’s faces were smeared with a red pigment during the ceremony before their chests had been cut open, most likely to remove their hearts.Remains showed that these kids came from different regions and when the children and llamas were sacrificed, the area was drenched with water. “We have to remember that the Chimú had a very different world view than Westerners today. They also had very different concepts about death and the role each person plays in the cosmos, perhaps the victims went willingly as messengers to their gods, or perhaps Chimú society believed this was the only way to save more people from destruction” said anthropologists Ryan Williams.

Not all Andean cultures were willing to offer their loyalty to the Incas as they expanded their empire because many were openly hostile. The people of the Chachapoyas culture were an example of this, but the Inca eventually conquered and integrated them into their empire. Archaeologists led by Gabriel Prieto revealed the largest mass child sacrifice with more than 140 children skeleton and 200 Llamas dating to the Chimú culture after he was informed about some children had found bones in a dune nearby Prieto’s fieldwork in 2011. According to the researchers' notes in the study, there was cut marks on the sterna, or breastbones some of the children and the llamas. Children’s faces were smeared with a red pigment during the ceremony before their chests had been cut open, most likely to remove their hearts.

Many species of the second major avialan lineage to diversify, the Euornithes (meaning "true birds", because they include the ancestors of modern birds), were semi-aquatic and specialised in eating fish and other small aquatic organisms. Unlike the Enantiornithes, which dominated land-based and arboreal habitats, most early euornithes lacked perching adaptations and seem to have included shorebird-like species, waders, and swimming and diving species. The latter included the superficially gull-like Ichthyornis and the Hesperornithiformes, which became so well adapted to hunting fish in marine environments that they lost the ability to fly and became primarily aquatic. The early euornithes also saw the development of many traits associated with modern birds, like strongly keeled breastbones, toothless, beaked portions of their jaws (though most non-avian euornithes retained teeth in other parts of the jaws).
