Mayas - Stairs that tell Histories



MEXICO – In the archaeological site of El Palmar, southeast of Campeche, a staircase of hieroglyphs was discovered by researchers at the National Institute of Anthropology and History (INAH) associated with the University of Arizona and to Mexican National Autonomous University (UNAM). Preliminary analyses have indicated that this pre-Hispanic city was in contact with the cities of Calakmul (Mexico) and Copan, Honduras. The finding has a thousand and three hundred years.

This is not the only staircase carved, decorated with hieroglyphics found in the lowland Maya. Twenty of this kind were cataloged. Evidence of the monument were first found in 2009 among others, which are called Grupo de Guzman. At the time, the evaluation of the stones "in situ" suggested the existence of a stairway.

The field season began in late 2010 and early 2011. According to archaeologists, Javier Lopez and Camacho Kenichiro Tsukamoto, the first four pieces examined, were in good condition, while two others were fragmented. It was necessary to do emergency procedures for conservation.

All blocks, drawings, and specific location of the find were photographed and examined with instruments like a topografic laser, before being transferred to archaeological camp with safety. The INAH's restorers: Yareli Jaida and Diana Leticia Jiménez Arano determined the level of conservation and are working in restoration of the blocks.




Hieróglifos

A preliminary translation of hieroglyphics, led by epigraphist Octavio Olguin Esparza (UNAM) provides important information for understanding the Maya Classic period (250-900 AD). The hieroglyphic stairway relates, among other historical events, the visits by foreign to El Palmar. The events are marked in a calendar. The date shown is "11 Ajaw Sak 18" or 13 September of 725 AD. The stone document also refers to the 'Lords of place' and the contacts they had with cities such as Copan and Calakmul, in the southern of the region that was occupied by ancient mayas.





During the excavations, was discovered a large room whose floor shows signs of having been burned, which indicates the possibility of perform of rituals. There were also fragments of pottery. A funerary instalation with offerings was also found. There were human bones and two objects of polychrome pottery. The anthropologist Jessica Cerezo-Roman, University of Arizona determined that the mortal remains belong to a mature man, as indicated the examination of the jaws and the inlays of jade on the front teeth.

The Giant Scorpions



Paleontology – Analyses performed on the fossil of a giant scorpion 417 million years old, a species extinct (thank goodness!) revealed traces of a substance called chitin in the exoskeleton of the creature. This finding demonstrates something that until now was considered impossible: The age of the chitin found, is several hundred million years older than what was considered the maximum possible in terms of conservation of this material.

The discovery was made ​​by a team of scientists led by George Cody of the Carnegie Institution of Washington. Analyses were conducted at the ALS (Advanced Light Source) at Lawrence Berkeley National Laboratory in California

The work of these experts contradicts the classical idea that the organic material can not be mantained for so long because it would be decomposed by microorganisms. However, scientists have found a fibrous mesh of chitin in the fóssil. Chitin is a polysaccharide rich in nitrogen.

Some species of these huge animals had reached over two meters in length. Chitin was also found in younger fossils, like a scorpion 310 million of years and even others, with 25 million years. The size of the giants scorpions is a frightening demonstration that in the past, arachnids, insects, crustaceans and other creatures were much larger than today. It is known that Eurypterids are aquatic ancestors (and extinct) of land scorpions and possibly of all arachnids of today.

Rhinoceros: The stolen horns




PORTUGAL – At Coimbra town, on Tuesday – 19, two horns of rhinoceros of the eighteenth century were stolen from the Museum of Science, University of Coimbra. Authorities believe the theft was an act of a international gang which operates in the black market, where these horns can reach the price of 80 000 euros.

The robbery happened at the section of zoology at around 17.00 at a closed section of the gallery. Museum director commented: We believe that this is a work of an international gang because thefts similar to this have occurred in other museums. Theft of rhino horns are happening some years ago. They started in South Africa this year, the latest happened in the UK, (in February) in an antiques shop in Essex and in the Museum of Natural History at Rouen in March in France.

The destination of the goods is Asia, where these horns are used in the preparation of aphrodisiacs. But the director of the Museum warns: These horns are impregnated with toxic products used for its conservation. Are poisonous for human consumption.

The past encaged on a crystalline stone



PERU – In Chiclayo (a town located at northwest of Peru, capital of Lambayeque region, one of the 25 political divisions of the country) scientists found several examples of small insects preserved in amber stones. Researchers believe that these tiny specimens lived around 20 millions of years ago. Were – therefore, contemporary of the dinosaurs and, they passed, at least, for a glaciation.

In the stones of amber insects like Psocoptera, Diptera, Coleoptera, Hemiptera and spiders, as well as spores, pollen fossils, and even a drop of blood and hair of rodents, all of these fragments of the past remained preserved.

The discovery was made ​​on a beach in far north of Peru by paleontologists from the Paleontological Museum Meyer-Honningen. The team found more than a hundred stones, among the river sediments, but still could not identify the majority. Some of the insects are nor even known, like the , long-legged mosquito Zancudo or a wasp, that has the stinger in the front of its body. These are possibly species already extinct that indicate changes in the flora and fauna of the area.

However, the Peruvian museum has invited Austrian scientists to assist in the study of fossils and new expedition will be made in the Santiago River, for try to uncover new clues about the evolution of the Amazon.
