Gastornis
Gastornis parisiensis measured on average 1.75 metres (5.7 ft) tall, but large individuals grew up to 2 metres (6.6 ft) tall. Gastornis had a huge beak with a slightly hooked top, which possibly suggests that it was carnivorous. Gastornis had large powerful legs. It had large feet with small talons. Fossil footprints suggest it was a herbivore.
