Struthio anderssoni

Struthio anderssoni was a large ostrich with an estimated mass of 270kg, laying eggs of up to 2400 cm3 in volume. The eggs are larger than those of living ostriches, measuring 16.6-18.8 cm in length and 13.7-15.8 cm in width, with an estimated mass of 1.89 – 2.8 kg. In 2023, based on a re-examination of cast of a femur, it was suggested that this species be moved to the genus Pachystruthio. ==References==
