Genyornis is a genus of thunderbirds (Dromornithidae) that wasextinctin the Pleistocene and livedin Australia and suddenly became extinct about 47,000 years ago. The only known species Genyornis newtoni was named after the English zoologist and ornithologist Alfred Newton . Genyornis is the only genus of thunderbird that still lives in the Pleistocene. Fossils of the genus have been found in all Australian states. Genyornis is also the only species of thunderbird to have a skeleton found in an anatomical context.

features

Genyornis was 2.0 to 2.15 meters high, weighed about 290 kg and was therefore a medium-sized thunderbird, smaller than Bullockornis planei and Dromornis stirtoni but larger than Ilbandornis woodburnei . The skull of Genyornis was conical, the beak less high and less flattened laterally than that of Bullockornis and Dromornis . It is likely that the bird ingested gastroliths to break up the food mainly consisting of leaves that were found with some skeletons.

die out

Research on burned Genyornis eggshells found in more than 200 locations across Australia shows that the population suddenly collapsed about 47,000 years ago. Genyornis likely became extinct because Aboriginal people collected their eggs, fried them in fires, and ate them.
