What was Fukuiraptor?

Fukuiraptor was a predatory theropod from Early Cretaceous Japan. It is usually discussed among megaraptorans, a group notable for large hand claws. Its name includes raptor, but that does not place it in the same family as Velociraptor.

What makes the fossil distinctive?

The known material includes a partial skeleton and bones assigned from additional individuals. Many specimens are immature. Adult size cannot simply be read from the smallest fossil, and estimates depend on how much growth remained.

Where was it found and how was it named?

The genus was named in 2000 from the Kitadani Formation in Fukui Prefecture. Large claws initially contributed to confusion about its identity. Establishing whether a claw belongs to the hand or foot is essential because superficially similar structures can have different anatomical roles.

What can we infer, and what remains uncertain?

Comparisons with Australovenator help explain the megaraptoran interpretation. The precise position of megaraptorans within Theropoda has itself been debated, so a highly specific family label should not be presented as unquestionable. The strongest starting points are the preserved limbs, claws and teeth. They support a predator without revealing an exact hunting routine or maximum running speed.

Was Fukuiraptor a Velociraptor relative?

It was a theropod, but is generally placed among megaraptorans rather than the dromaeosaurid group containing Velociraptor.

How can you check the evidence?

The Paleobiology Database record catalogues Fukuiraptor under Neovenatoridae. Its linked bibliography identifies this research starting point: Y. Azuma and P. J. Currie. 2000. A new carnosaur (Dinosauria: Theropoda) from the Lower Cretaceous of Japan. Canadian Journal of Earth Sciences 37:1735-1753. Open the bibliographic record. A catalogue entry establishes the source trail; it does not independently verify every later illustration or behavioural claim.

Use the dated genus overview to follow the references behind the discovery and anatomy discussed above. When sources disagree, compare which specimen and rock layer each author studied. A reconstructed whole animal can combine original bones with comparisons to relatives; those two kinds of evidence should not be confused. The account above explains the particular limits that matter for Fukuiraptor, rather than supplying unsupported size, speed or lifespan figures.

Read the image and keep exploring

The Fukuiraptor mount shows a predatory theropod skeleton, with large hand claws distinct from a raptor-style foot claw. A displayed specimen or skeletal mount can include restored parts. Its appearance should be read alongside the original specimen description.

Quick answers

Where have Fukuiraptor fossils been found?
The discoveries discussed here come from Japan. Modern place names describe discovery locations, not a complete ancient geographic range.
When did Fukuiraptor live?
It is placed in the Cretaceous period. See the discovery discussion for qualifications about the particular rock layers and dating.
Where can I compare Fukuiraptor with related dinosaurs?
Follow the related field notes below. Comparisons explain shared anatomy; they do not imply that all the animals lived together.
