Oldest Embryos Dinosaur Fossil

Palaentolog has identified the oldest dinosaur embryos from a species that lived approximately 190 million years ago. Embryos are included on subbangsa dinosaur eggs called Massospondylus. 

This type is a member of a group of dinosaurs called prosauropods, the ancestors of the true sauropods, which has four big feet and long neck.

In fact, eggs have been found in South Africa since 1976, but only identified recently. The result of his own research published in the Journal of Vertebrate Palentology recently. In his research, the researchers succeeded in identifying the early development of the embryonic type of dinosaur.

Using the study of embryonic development, the researchers were able to estimate the shape of dinosaurs that when born. Through analysis, researchers say that the embryo is found it's actually about to be born. But because its mother died, she did not have the chance of birth.

Interestingly, the characteristics of the embryo is different from an adult dinosaur. When born, dinosaur species would have a longer front legs so that required him to walk on four legs, unlike the adult figure that walked on two legs. Head of the embryo also appeared out of proportion because it is too large when compared to their bodies. Though the figure of an adult has a relatively small head and long neck. Dinosaurs it seems to change with increasing age.

Ressz and Dr. Diane Scott, his assistant who was involved in the research, spend a few months to prepare the specimens. "The material is very fragile. It is very difficult to do and there is a risk of damage to the embryonic material is very old," said Dr Resiz on the BBC website. "The specimen is the oldest specimen owned and never touched by all the staff of the University of the Witwatersrand until we were interested in doing," said Reisz.

In his research note, they predict that when born, the embryo that will require care and protection of parents (parental care), just like humans. If the allegation is true, then this animal is an example of the oldest animal in need of parental care and protection.

Forbidden Statue Period Nazi Discovered

Treasure trove of statues forbidden in the Nazi era discovered in the basement of a demolished building was bombed during World War II. German museum officials announced the discovery on Monday (8/11/2010) ago.

Mayor of Berlin, Klaus Wowereit, said pleased with the discovery. The plan, the sculptures will be exhibited at the Archaeological Museum of Berlin, located only 1 kilometer from the place of discovery.

"We should be proud of this invention. Questions about the owner of the statues were relatively unimportant," said Wowereit.

Eight of the 11 statues found have been identified as the work of an artist named Otto Baum, Otto Freundlich, Karl Knappe, Marg Moll, Emy Roeder, Edwin Scharff, Gustav Heinrich Wolff, and Naum Slutzky. Meanwhile, three other statues have not been identified.

In the Nazi period, this statue is believed to be part of one of the museums in Germany. The statues were then seized and exhibited by the Nazis in Munich and other cities as degenerated art or art that deserves ridicule cheap.

Archaeologists discover statues when they were trying to find the remains of collapsed buildings of the 13th century. "When we found him, we thought we had found the remains of the 13th century. However, we found items that this art is called degenerated. Shocked," said Mathias Wemhoff, archaeologist and director of the history museum in Berlin.

Experts suspect that the statues are a few things that are saved by Erhard Oewerdieck, a tax inspector who was given the task by the Holocaust museum Yad Vashem for saving Jews during World War II.

Discovered World's Oldest Stone Axe

A group of archaeologists found a stone ax was about 35.500 years in Amhem Land, an area of 97.000 square kilometers located in the north of Darwin, Australia and an Aboriginal sacred land. Ax found in a type of edge ground axes, namely the type ax sharpened so that the edges sharper. Ax is claimed is a kind of edge ground axes of the oldest, defeated a similar hatchet between 20000-30000 year-old found in Japan and other parts of Australia before.

Bruno David, Monash University scientists who discovered these axes explain the evidence that the hatchet is a ground edge. "We can see the sign at the edge of the ax. People who use it mengasahnya hatchet with stone so that its surface is more subtle," said David as reported by the Discovery site on Friday (5/11/10) last.

David said that the findings could undermine the view that the hatchet came from Europe. "The meaning of this discovery is that we can know that the conventional view that states ax comes from Europe does not apply globally. We must think differently," he explained.

In addition, this study also could be evidence that the Aborigines who inhabited the region Jawoyn has developed technologies that support life. "Grinding stones indicate the existence of technologies that increase efficiency. The discovery of this technology is equivalent to finding a bow and arrow," David said.

Members of the Aborigines who had invited the archaeologists to the holy land, said the study could open a very significant relationship with the ancestors. "I want to know the truth (about the stone ax). Now I already knew it. I feel happy," said Margaret Katherine, landowners in Amhem Land.
