Archeopteryx It is a genus of dinosaurs, like feathered birds, that lived during the Jurassic period about 150 million years ago.
3 species and over 10 specimens Archeopteryx It is now all known from Bavaria, Germany.
It is considered the first known bird, Archeopteryx It had primitive properties like teeth and long bone tails, and was similar in size to Eurasian magpies.
“Archeopteryx Dr. Christian Foss, a paleontologist at Friborg and Rostock University, and his colleagues, said:
“To date, this taxa is known only from the lower Titonians of Bavaria in Germany. Nine of the 11 specimens currently known as this genus have been excavated from the Altmühltal Formation.”
“Morphological variation, such as dentition and limb proportions – suggestions within the genus Archeopteryx They may experience evolutionary changes and be divided into different species during this period. ”
“For over 150 years, the genus Archeopteryx “It was the only Jurassic representative that could be introduced to the Pareve, the theropod clade, which includes the bird and its closest parents, Doromaosaurid and Trudontid,” they added.
“Discovering diverse communities of Pallavia packaging from slightly older rocks in northeastern China over the past decades, identification of fragmented harem specimens. Archeopteryx As another taxa, Ostromia Classicesand discovery Alcmonavis Poeschlielucidated the previously unexpected complexity of the evolution, diversity and distribution of Pallavia in the late Jurassic period. ”

new Archeopteryx The specimen – a fragmentary skeleton – was discovered in May 2019 in the Mörnsheim Formation in Mörnsheim, Baibaria, Southern Germany.
“The skeleton is the third Aviala specimen found in the Mörnsheim formation,” the paleontologist said.
“It consists of fragments of both the right forelimb and shoulder, left forelimb and both the hind limb.”
Unofficially called Karlsruhe specimen, the new fossil is about 149 million years old, and is the 12th specimen representing it Archeopteryx Genus.
“The specimens are within the size range of specimens for Dating, Munich, Thermopolis and feather wings and therefore represent one of the medium sizes. Archeopteryx Samples,” the researchers said.
Their paper It was published in the journal in January 2025 Fossil Record.
