MEET THE ANIMAL
Meet Australovenator
Australovenator was a meat-eating dinosaur from Queensland, Australia. Its museum profile follows revised dating of the fossil-bearing Winton rocks to roughly 93 million years ago, in the Late Cretaceous. That age is younger than the original interpretation. The change shows why geological dating must stay connected to the particular rocks around a fossil. [D4]
Its hands carried three fingers and enlarged curved claws. These were hand claws, rather than the large second-toe claw associated with some familiar raptors. Newly recovered arm and wrist bones from the original specimen added details that had been missing. Studying those actual elements gives a firmer picture than borrowing the hands of a different dinosaur. [D2]
Researchers fitted the forelimb bones together to investigate their possible movement. The resulting models suggest substantial bending and grasping potential, but missing cartilage and other soft tissues limit the exact range of motion. A possible grasping action does not record how prey was handled. Australovenator's arms are unusually informative because preserved bones let researchers test movement ideas while keeping the uncertain parts of the reconstruction visible. [D3]

How to read the evidence
Source supported identifies a description documented by the cited source. Inferred marks a reconstruction or functional estimate. Debated marks competing interpretations. Not established means the sources reviewed for this dossier do not support a firm conclusion; it does not mean a behavior never occurred.
A size reference is an estimate, not a population range. Nesting evidence does not by itself establish courtship, mate choice, or lifelong pairing.
Body mass
InferredAbout 314 kg (limb-scaling model)
Measured-circumference estimate. Dataset specimen entry is only 'AAOD', with no inventory number or maturity assessment; not an adult average. [D5]
Diet and feeding
InferredMeat-eating with serrated teeth
Recurved, compressed tooth crowns support a cutting dentition. Sharing a fossil deposit with a sauropod does not prove a predation event. [D1]
Habitat and setting
Source supportedWinton Formation, Matilda Site
The Queensland holotype occurs in fine sediment interpreted as abandoned-channel or billabong fill. Later zircon-based dating shifts this material into the Late Cretaceous, rather than the original latest-Albian interpretation. [D1] [D4]
Movement
InferredBipedal reconstruction; mobile grasping arms
Hindlimbs support a two-legged reconstruction. Forelimb articulation models indicate substantial flexion and grasping potential; missing cartilage limits exact motion, and no speed is assigned. [D1] [D3]
Recognizable anatomy
Source supportedThree fingers with enlarged manual claws
Additional holotype arm and hand elements document large recurved claws and the wrist. These are hand claws, not an enlarged dromaeosaur-style toe claw. [D2]
Reproduction & life together
Reproduction and nesting
Not establishedNot established here
Focused egg, nesting and bone-histology searches did not establish assigned Australovenator eggs, parental care, clutch size or breeding maturity.
Mating and courtship
Not establishedNot established here
Reviewed osteological and movement studies do not establish sexual dimorphism, pairing or courtship; focused reproductive searches yielded no direct demonstration.
Social behavior
Not establishedNot established here
At Matilda Site, Australovenator and a sauropod occur with aquatic vertebrate remains. This depositional association does not establish packs, cooperation or a witnessed hunt. [D1]

THE STORY IN THE FOSSILS
Hands with a wide range of motion.
New arm elements recovered from the holotype site made Australovenator's hands unusually informative. Bone articulation suggests they could pull inward and grasp; soft tissues remain a constraint on exact range of motion and prey-handling reconstructions. [3]
Dating also matters. Zircons from the fossil-bearing Winton rocks support an age of roughly 93 million years in the museum's revised account, considerably younger than the original age assignment. The catalog follows that later geological context. [4]
A note on scale and time
The dossier identifies the scope of each reference estimate. A mount, an individual fossil and a species-wide adult range are different measurements. Comparison metrics remain unavailable where adult scope has not been established. Unknown does not mean zero.
