¨
A new feathered gliding
dinosaur named Jian changmaensis was announced on 4 June 2026 in a study
published in the Annals of Carnegie Museum.
¨
The fossil is
approximately 120 million years old and was discovered in the Changma Basin,
Gansu, China.
¨
Jian changmaensis belongs
to Microraptoria, a group of small predatory theropod dinosaurs within the
broader dromaeosaurid family.
¨
Microraptors are Early
Cretaceous dinosaurs and are closely related to Velociraptor.
¨
The fossil shows long
feathers on both forelimbs and hind limbs, giving it a four-winged appearance.
¨
This body structure is
interpreted as an adaptation for gliding rather than powered flight.
¨
The estimated wingspan
was about four feet, comparable to a barn owl.
¨
Similar four-winged
adaptations have been observed in other microraptor fossils from northeastern
China.
¨
The Changma Basin is an
important site for Early Cretaceous vertebrate fossils, including bird remains
such as Gansus yumenensis.
¨
The basin has also
yielded clusters of broken bird bones, suggesting possible predatory activity
within the ecosystem.
¨ Jian changmaensis is the only confirmed microraptor fossil found outside northeastern China.
¨ This discovery extends the known geographical distribution of microraptors within Asia.
