Briefings

Scientists revealed that Earth lost over a billion years of geological history due to tectonic activity during supercontinent breakup, creating the Great Unconformity. Researchers also identified two octopus squeezing strategies and proposed that the British king Verica was a female queen misgendered by historians. The study highlights how Earth erases its own record and challenges traditional gender assumptions in ancient history.

Key points

• Earth lost more than a billion years of geological strata due to tectonic activity during supercontinent breakup, creating the Great Unconformity.
• Octopuses use two primary squeezing strategies: 3-step and 4-step methods, where body compression differs from arm movement.

Context

The Great Unconformity represents the largest gap in Earth's geological record, erasing over a billion years of strata. This finding, published in Nature Earth, suggests the missing layers were erased by global tectonic processes. The study also examines octopus navigation strategies and proposes a re-evaluation of the gender of the British king Verica based on Latin naming conventions.

Limitations

The Great Unconformity's exact cause remains debated, with limited global model comparisons. Octopus studies are limited to two species in controlled laboratory settings. Verica's gender is not confirmed by archaeologists, and the article does not specify the publication location.
