long-gone mollusk comes to life with 3d printer

Scientists have created a long, lifelike model.
Extinct marine life using a 3D printer. The oval-Animal shape
A multi-placenta called anus-
Crawling under the sea 0. 39 billion years ago, there was only one suctionlike foot.
It also has a magnificent armor of hard plates, surrounded by a circle of thorns, but scientists are not sure exactly how these features are arranged.
Most of the known multi-site fossil specimens of animals have been destroyed and rotted.
In fact, scientists do not know how multiplate cells, distinguished from 17 plates, are related to multiplate cells (
Also known as chitons)
Another group of armored software animals
To find out, a team of researchers used a microcomputer. tomography (CT)
Scan the fossil fragments of prehistoric mollusks found 10 years ago in Ohio.
The scan gave scientists a vivid look at the shell of the creature and the original position of the thorn;
The researchers also created a third using scanning technology.
The animal is cast in the size of its reconstructed shape.
With this information, along with the details of the lives of relatives of this software group, the researchers produced a multi-color texture model made of clay, resin and silica gel.
Results: What did the software look like millions of years ago. [

The species has been discovered by private collectors and co-owners over the past decade.
The author of the study, George Kanpur, donated the fossils to the Cincinnati Museum of Natural History.
Results of the new study, detailed report.
18 in the journal Paleontology, people are helping to place multi-host plants on evolutionary trees, revealing
In fact, the software that has disappeared is a group of software animals.
\"We can now prove that people in multiple places are distant relatives of modern Millennium insects, which did not evolve until the later stages of Earth history, \"Jacob, a researcher at the University of Texas at Austin, said in a statement.
\"We can also prove that they have evolved many features in some modern Millennium worms.
\"Research reported in detail last year in the Journal of Contemporary Biology found that vision is such a feature: West India fuzzy lasagna (
Acanthorpleura granulata)
It\'s 3 inch (
Nearly 8 centimeters)
Up to hundreds of eye-like structures can make predators lurking above disappear.
However, scientists say the vision may have only appeared in the past 25 million years, thousands of times lower than the human vision.
