The Discovery
Researchers associated with University College London have identified a new prehistoric predator by re-examining a long-overlooked museum specimen. The fossil was originally gathered on the Isle of Wight and added to the collection at the Natural History Museum in 1924, but it sat unstudied for decades. Details of the identification were published in the scientific journal Royal Society Open Science.
What Scientists Found
The newly described species has been given the scientific name Invictibellatrix amberina. This long-clawed theropod inhabited ancient Britain during the Early Cretaceous period, approximately 120 million years ago. Reaching lengths of up to four meters, the dinosaur possessed several distinctive traits:
- Large arms bearing prominent, curved claws.
- A build that was smaller and more nimble than that of its relative, the Tyrannosaurus rex.
- Physical attributes suited for hunting medium-sized prey.
Lead study author Dr. Cassius Morrison explained that although it was not the dominant apex predator of its ancient environment, it would have been extraordinarily dangerous to humans had they coexisted. Because humans would have represented perfectly sized targets, this agile carnivore would have actively chased them, whereas a massive T. rex would not have bothered.
Why It Matters
This breakthrough offers the very first direct evidence that megaraptorans lived in Europe. Study co-author Charlie Scherer noted that these dinosaurs likely originated in Asia, moved across Europe, and reached the ancient supercontinent of Gondwana through this route rather than island-hopping further south. Megaraptorans later expanded and evolved into top predators in landmasses that correspond to present-day South America, Africa, and Antarctica.
