The newly identified genus, Koreaceratops hwaseongensis, lived about 103 million years ago during the late Early Cretaceous period. The specimen is the first ceratopsian dinosaur from the Korean peninsula.
The partial skeleton includes a significant portion of the animal's backbone, hip bone, partial hind limbs and a nearly complete tail. Results from the analysis of the specimen were published in the 18 November 2010 online edition of the journal Naturwissenchaften: The Science of Nature.
The Koreaceratops hwaseongensis is named for Korea and Hwaseong City, which yielded the fossil. It was discovered in 2008 in a block of rock along the Tando Basin reservoir. It is one of the first articulated dinosaurs known from Korea.
"This is a rare find," said Michael J. Ryan, Ph.D., curator and head of Vertebrate Paleontology at The Cleveland Museum of Natural History, who co-authored the research. "Fossils of dinosaurs have not typically been found in this region, whereas evidence of dinosaur eggs and footprints occur more commonly. This specimen is significant because it fills in a missing 20 million-year gap in the fossil record between the origin of these dinosaurs in Asia and their first appearance in North America."
At approximately 5 to 6 feet long and weighing about 60 to 100 pounds, the animal was relatively small compared to the geologically younger, giant relatives like Triceratops found in North America. Koreaceratops had a parrot-like face with a beak at the front of its jaws, indicating it was an herbivore. The claws on its hind feet suggest that it was bipedal and moved at a fairly rapid speed. Koreaceratops had a unique fan-shaped tail formed by long neural spines, which suggests it may have been a good swimmer, and spent part of its time hunting for aquatic food.
Yuong-Nam Lee of the Korea Institute of Geoscience and Mineral Resources was lead author on the research. Yoshitsugu Kobayashi of the Hokkaido University Museum in Japan was third author.

Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Applied Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in switching on a current with a desired direction in graphene using a single laser pulse within a femtosecond ¬¬ – a femtosecond corresponds to the millionth part of a billionth of a second. This is more than a thousand times faster compared to the most efficient transistors today.
Graphene is up to the job
At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...
