Lizards have been shedding tails to stay safe for 99 million years, Israeli research finds
Israeli research reveals that lizards have practiced voluntary tail-shedding for 99 million years. Scientists studying a tiny lizard tail trapped in amber from northern Myanmar found direct fossil evidence of this defensive escape mechanism, which living lizards still use against predators today. Tel Aviv University researchers made the discovery, marking the first direct proof of the tactic dating back to the age of dinosaurs. Investigators remain uncertain what specifically triggered the prehistoric shedding event or whether the animal successfully escaped its predator.

Ancient Amber Discovery Shows Lizards Shed Tails 99 Million Years Ago
Israeli research reveals that lizards have practiced voluntary tail-shedding for 99 million years. Scientists studying a tiny lizard tail trapped in amber from northern Myanmar found direct fossil evidence of this defensive escape mechanism, which living lizards still use against predators today. Tel Aviv University researchers made the discovery, marking the first direct proof of the tactic dating back to the age of dinosaurs. Investigators remain uncertain what specifically triggered the prehistoric shedding event or whether the animal successfully escaped its predator.
Why it matters
Tracing the evolutionary origins of tail-shedding has historically proven difficult for paleontologists due to the scarcity of direct fossil evidence. Preserved amber samples provide exceptional detail that skeletal remains alone cannot capture, offering a window into ancient animal behavior. This finding confirms that a prominent survival strategy observed in modern reptiles was already well-established during the Cretaceous period.
What is confirmed
- Lizards have been shedding tails to stay safe for 99 million years, according to Israeli research.
- The lizard tail was discovered preserved in amber from northern Myanmar.
- The discovery provides direct fossil evidence of voluntary tail-shedding used by lizards during the age of dinosaurs.
Still unconfirmed
- Researchers do not know what caused the ancient lizard to shed its tail or whether it successfully escaped.
What to watch next
- Discovery of additional amber specimens containing related fossil evidence
- Further analysis from Tel Aviv University regarding the specific lizard species involved
