Đã hiểu vì sao "cậu nhỏ" nhỏ

Giant (khổng lồ) millipedes (động vật nhiều chân) as long as a car and weighing 50kg once hunted across northern England, experts have said, following the discovery of a 326 million-year-old fossil (hóa thạch).

The fossil was found by "fluke" (sự may mắn) when a section of a cliff fell at Howick Beach in Northumberland and was discovered by a former PhD student.

Experts said in order to get so big, the creature, known as Arthropleura, must have found a nutrient-rich plant diet and may even have been predators (thú săn mồi), feasting on other invertebrates (loài không xương sống; người nhu nhược) or small amphibians (loài lưỡng cư; thủy phi cơ, xe tăng lội nước).

Only a section of the fossil has been found, according to experts.

They believe the specimen is a section of the creature's exoskeleton (bộ xương ngoài) that it shed near a river bed, which was then preserved by the sand.
