Phorusrhacos longissimus
A tall flightless predator used a deep hooked beak to strike prey on the ground.
Argentavis magnificens
Argentavis magnificens was a giant bird from Late Miocene Argentina. Its flight is reconstructed from incomplete fossils and aerodynamic models, not observations of a living bird.
Genyornis newtoni
This two-meter flightless bird had a deep jaw and powerful legs, probably feeding on soft leaves, fruit and shoots.
Pelagornis sandersi
Its estimated wingspan exceeded six meters, while bony pseudoteeth lined a beak adapted to slippery marine prey.
Gastornis parisiensis
This giant flightless bird had a massive beak, but evidence favors a mainly herbivorous diet.
Teratornis merriami
A large soaring bird with an estimated 11–12 ft wingspan; its diet involved more than a simple vulture comparison.
Lithornis vulturinus
A strong flyer belonged near lineages whose living members are mostly flightless.
Dromornis stirtoni
Three meters tall with a massive beak, it was among the heaviest birds.
Kelenken guillermoi
A seventy-centimeter skull and hooked beak armed one of the largest terror birds.
Icadyptes salasi
A one-and-a-half-meter penguin lived near the equator with a spear-like beak.
Anthropornis nordenskjoeldi
At almost 1.8 meters, it was a giant diver on a warmer Antarctic coast.
Brontornis burmeisteri
Brontornis burmeisteri was a giant flightless bird with exceptionally robust hind limbs.
Dasornis emuinus
A near-six-meter wingspan and bony pseudoteeth armed a giant seabird.
Bathornis grallator
Long legs and a strong beak belonged to a terrestrial bird with little or no flight.
Paraphysornis brasiliensis
A deep beak and massive legs made a heavyweight South American terror bird.
Psilopterus bachmanni
A lighter terror bird had long toes suited to rapid pursuit.
Llallawavis scagliai
Its complete inner ear reveals sensitivity to relatively low-frequency sound.
Eremopezus eocaenus
Robust leg bones belonged to a giant flightless African bird whose skull remains unknown.
Inkayacu paracasensis
A near-human-height diving bird preserves feathers and melanosomes that opened direct study of ancient penguin color.
Kairuku grebneffi
A slender trunk, long bill and large flippers produced a taller silhouette than modern penguins.
