Mullerornis modestus is an extinct species ofelephant bird, and the only member of the genusMullerornis.

Taxonomy

[edit]

The genusMullerornis was described in 1894 byAlphonse Milne-Edwards &Alfred Grandidier.[2] The genus is named after Georges Muller, a French explorer, who was killed in 1892 by hostile members of theSakalava people.

Synonyms ofMullerornis modestus

  • Mullerornis betsileiMilne-Edwards & Grandidier, 1894[3] (Betsileo elephant bird)
  • Mullerornis agilisMilne-Edwards & Grandidier, 1894 (agile/coastal elephant bird)
  • Mullerornis rudisMilne-Edwards & Grandidier, 1894[1] (robust elephant bird)
  • ?Mullerornis grandisLamberton 1934 (holotype destroyed in a fire in 1995)

Size comparison ofMulleornis (in pink) as well as other elephant bird species compared to a human

Mullerornis is smaller than the more well-knownAepyornis,[4][5] with a still substantial body mass of approximately 80 kilograms (180 lb).[6] A bone possibly belonging toMullerornis has beenradiocarbon dated to about 1260BP,[7] suggesting that the animal was still extant at the end of the first millennium.[8]Aepyornis modestus was shown by Hansford and Turvey (2018) to be a senior synonym of all nominalMullerornis species described by Milne-Edwards and Grandidier (1894), resulting in the new combinationMullerornis modestus.[9]

Palaeobiology

[edit]

Nocturnality

[edit]

Like other elephant birds and itskiwi relatives,Mullerornis probably was nocturnal based on the small size of its optic lobes, though it shows less optical lobe reduction than these other taxa, implying slightly morecrepuscular habits.[10]

Diet

[edit]

Isotopic evidence suggests thatMullerornis was likely abrowsing herbivore.[11]

Reproduction

[edit]

The eggs ofMullerornis are substantially smaller than those ofAepyornis, weighting approximately 0.86 kilograms (1.9 lb), with a shell thickness of about 1.1 mm (364 in).[6]
