HALLAZGO – A flower of tens of millions of years preserved in Burmese amber

Investigators from the State of Oregon University have identified a new genus and species of spectacular flowering of the Cretaceous period, converged in time by the Burmese amber.

“This is not a flowering flower, but it is a beauty, especially considering that it was part of a forest that existed 100 million years ago”, said George Poinar Jr., Professor Emeritus of the Faculty of Science at OSU (Oregon State University) . The hallazgos are published by the Journal of the Botanical Research Institute of Texas.

“Masculine flora is diminuta, of a 2 millimeters of ancho, but it has 50 stems disposed like a spiral, with antlers pointing to the sky”, dijo in a Poinar communication, an international expert and the use of plant life forms and animals preserved in amber to obtain more information about the biology and ecology of the past.

A stem consists of an anther, the cabeza producing poles, and a filament, the figure that connects the anther with the flower. “It’s easy to be so small, the detail that is awesome”, dijo Poinar. “Our specimen is probably part of a group in the plant that contains many similar flowers, probably women”.

The new discovery has a cup of flower eggs in the form of a egg, part of the flower of which the stems grow; an exterior cap that consists of six components in the form of known petals such as teapots; and anteras of two chambers, with sacks of poles that are open median valves with lateral bisagras.

Poinar and collaborators of OSU and the Department of Agriculture of EE.UU. nombraron a la nueva flor Valviloculus pleristaminis. Valva is the Latin term for high in an obese, locus significant compartment, many referring to many and estaminis reflecting the sexes of the sexual organs of the floor.

The flower covered in amber in the ancient continent of Gondwana and was transported across a continental shelf to 6,000 kilometers across the ocean from Australia to the southernmost Asian, dijo Poinar.

The geologists have been debating just when this earthquake, known as the Occidental Burmese Block, separated from Gondwana. Some of them are 200 million years old; Others claim that there are more than 500 million years ago.

If he finds numerous angiosperms in Burmese amber, the majority of the figures are described by Poinar and a colleague from the state of Oregon, Kenton Chambers, who also collaborated on this investigation.

The angiosperms are vascular plants with numerous, large and tall plants, which fertilize and develop inside the flower.

Given that the angiosperms are only evolving and are being diversified 100 million years ago, the Western Burmese Block does not have separate Gondwana antes, dijo Poinar, which is much slower than the fecal sugars by the geologists.
