Shingopana (meaning "wide neck" in Swahili) is a genus of titanosaurian sauropod from the Middle Cretaceous Galula Formation of Tanzania. It is known from only the type species, S. songwensis.[1] Gorsak & O'Connor's phylogentic testing suggest Shingopana is more closely related to the South American titanosaur family of Aeolosaurini than any of the titanosaurs found so far in North & South Africa.[1]

Discovery and naming[]

Part of the holotype was discovered in 2002 by scientists affiliated with the Rukwa Rift Basin Project, which was run by Patrick O'Connor and Nancy Stevens.[1] The rest of the skeleton was excavated during the following years. The genus was officially named in 2017.

Description[]

Shingopana was a quadrupedal Aeolosaurin sauropod that would have reached up to 8 meters (26 ft) long when fully grown, smaller than the average sauropod.

Skeleton[]

Skeletal

The holotype was damaged by insect bore holes shortly after the animal died.

Shingopana is known from a partial jaw, which somposes of much of the surangular and angular bones. Shingopana is also known from four cervical vertebrae; with two of these vertebrae having preserved cervical ribs and another isolated cervical rib. Instead of having spined vertebrae, Shingopana instead had balls of rough bone on top of the ribs, which probably helped to strengthen its neck.

Four ribs have been preserved with the holotype, but none are complete. The ribs had flanging edges, but their function is currently unknown.

A complete humerus is known and a partial femur has been discovered also. The femur is much shorter and squashed than that of the sister taxon Aeolosaurus. The legs had fewer attachment sites for muscles, makinf the legs less sturdy than other titanosaur species.

Classification[]

Shingopana has been classified witnin the Aeolosaurini. It has been added into the Aeolosaurini cladogram by Silva et al. (2019).[2][3][4]

Paleoecology[]

The holotype was discovered in the Middle Cretaceous Galula Formation, of the Rukwa Rift Basin, in Tanzania. It would have coexisted with the sauropods Rukwatitan[5] and Mynamawamtuka[6], the mesoeucrocodiles Pakasuchus[7] and Rukwasuchus[8], the mammal Galulatherium[5], an unnamed notosuchian, an unnamed turtle, an unnamed theropod[5] and two types of lungfish (Lupaceradotus and an unanmed genus).
