Forskare har identifierat en ny insektsart bevarad i 100 miljoner år gammal bärnsten från Myanmar. Den sanna insekten har ovanliga framben som slutar i stora, klorliknande strukturer som liknar krabbklor. Forskarna gav den namnet Carcinonepa libererrantes efter K-popgruppen Stray Kids.

Forskare vid Ludwig Maximilian-universitetet i München ledde studien av fossilet från Myanmars Kachin-region. De använde mikrodatoriserad tomografi för att skapa detaljerade 3D-bilder av insektens anatomi. Teamet jämförde klorna med mer än 2 000 liknande strukturer från både levande och utdöda arter.

Fossil claw reveals oldest known spider relative from 500 million years ago

Researchers have identified a 500-million-year-old fossil from Utah as Megachelicerax cousteaui, the earliest known chelicerate and relative of spiders, scorpions and horseshoe crabs. The discovery, detailed in a Nature study, extends the group's evolutionary history by 20 million years to the Cambrian period. A tiny claw uncovered during preparation confirmed its significance.

Jiangchuan Biota fossils in Yunnan reveal complex animals before Cambrian explosion

2 april 2026 Rapporterad av AI

More than 700 fossils from the Jiangchuan Biota in Yunnan Province, southwest China, dating 554-539 million years ago in the late Ediacaran, include early relatives of starfish, acorn worms, deuterostomes, and other bilaterians. Led by Dr. Gaorong Li of Yunnan University, the discovery—after nearly a decade of fieldwork—challenges the suddenness of the Cambrian explosion by showing diverse animal communities predated it. The results, published in Science (DOI: 10.1126/science.adu2291), feature exceptionally preserved carbonaceous films revealing fine details like digestive systems.

Tiny fossils identified as baby ankylosaurs after 20 years

21 april 2026 Rapporterad av AI

Small fossils of Liaoningosaurus paradoxus, once thought to represent a miniature species of armored dinosaur, have been confirmed as juveniles, including some less than a year old and a possible hatchling. Researchers analyzed bone growth patterns to reach this conclusion, challenging earlier ideas about the animal's size and lifestyle. The discovery provides insights into early development of ankylosaurs.
