Australodocus
Australodocus was a genus of sauropod dinosaur that roamed the Earth during the Late Jurassic period, approximately 150 million years ago. Its fossils were discovered in what is now Tanzania. While initially classified as a diplodocid, more recent analyses suggest it might belong to the titanosauriform clade.

About Australodocus
Australodocus is a genus of sauropod dinosaur that lived approximately 150 million years ago during the Late Jurassic period. Its fossils were discovered in what is now the Lindi Region of Tanzania, Africa, specifically within the Tendaguru Formation, a well-known fossil site for Jurassic dinosaurs.
Discovery and Naming
The remains of Australodocus were first recovered in 1909 during a German expedition led by Werner Janensch. The genus is based on two neck vertebrae, which exhibited distinct anatomical features compared to other known diplodocids. The genus name, Australodocus, translates to "southern beam," reflecting its initial classification as a southern relative of the North American dinosaur Diplodocus. The species name, bohetii, honors Boheti bin Amrani, a native crew supervisor and chief preparator who significantly contributed to the German expeditions.
Classification
Initially, Australodocus was described as a member of the Diplodocidae family due to the presence of double (bifurcate) neural spines on some of its vertebrae, a characteristic common among diplodocoid sauropods. However, subsequent analyses have proposed that Australodocus may actually belong to the titanosauriform clade, with some studies suggesting a close relationship to Brachiosaurus. Other research has placed it within the diplodocine diplodocids, closely related to Supersaurus and Dinheirosaurus, though the limited fossil material and taxonomic composition of analyses have made precise placement challenging. Some interpretations consider it a non-titanosaur somphospondyl, potentially an euhelopodid.
Size and Habitat
Estimates for Australodocus suggest a considerable size, with a length of about 17 meters (56 feet) and a weight of approximately 4,000 kilograms (8,800 pounds). The Tendaguru Formation, where its fossils were found, is thought to have been dominated by conifer forests, suggesting Australodocus inhabited such environments. This contrasts with the Morrison Formation in North America, which was characterized by open plains and low-browse flora.
Fossil Record
The fossil record for Australodocus is primarily based on two cervical vertebrae. While these vertebrae provide key diagnostic information, the scarcity of remains means that much about the dinosaur's complete anatomy, behavior, and lifestyle remains inferred rather than directly observed.

Frequently Asked Questions
What does the name Australodocus mean?
The name Australodocus means "southern beam." It comes from the Latin word 'australis' meaning "southern" and the Greek word 'dokos' meaning "beam," reflecting its initial classification as a southern relative of Diplodocus.
Where were Australodocus fossils found?
The remains of Australodocus were recovered from the Tendaguru Formation in the Lindi Region of Tanzania, Africa.
What period did Australodocus live in?
Australodocus lived during the Late Jurassic period, approximately 150 million years ago.
What did Australodocus eat?
As a sauropod, Australodocus was a herbivore, meaning it primarily ate plants.
How large was Australodocus?
Estimates suggest Australodocus reached a length of about 17 meters (56 feet) and weighed around 4,000 kilograms (8,800 pounds).
What is Australodocus's classification?
Australodocus was originally described as a diplodocid but later studies suggest it may be a titanosauriform, possibly closely related to Brachiosaurus.
Related Dinosaur species
Asilisaurus
Asilisaurus is an extinct genus of silesaurid archosaur from the Middle Triassic period, known from fossils found in Tanzania. It is considered one of the oldest known members of the Avemetatarsalia, the group of animals that includes dinosaurs and pterosaurs. Its discovery has provided valuable insights into the early evolution of dinosaurs and the diversification of archosaurs.
Alcovasaurus
Alcovasaurus is an extinct genus of herbivorous stegosaurian dinosaur that lived during the Late Jurassic period. Originally described as Stegosaurus longispinus, it was later reclassified into its own genus due to unique characteristics, particularly its exceptionally long tail spines. Its exact taxonomic placement has been debated, with some researchers considering it a distinct genus and others suggesting it might be a species of Miragaia.
Amphicoelias
Amphicoelias was a genus of herbivorous sauropod dinosaur that roamed the Earth approximately 150 million years ago during the Late Jurassic period. Known from fossils found in Colorado, United States, it was moderately sized, with estimated lengths of around 18 meters and a body mass of 15 metric tons. Its anatomy, particularly its vertebrae and limb bones, shares similarities with its close relative, Diplodocus.
