Romeo, Bolivia's last known Sehuencas water frog, has been calling unsuccessfully for a mate for nine years.
To draw attention to Romeo and the plight of his species, scientists have created Romeo an online dating profile -- just in time for Valentine's Day. "Not to start this off super heavy or anything, but I'm literally the last of my species," reads Romeo's profile.
Tiahuanaco sits high in the Andes at an altitude of around 2 miles above sea level.
The location is curious as a lake nearby to lake Titicaca, with which the site is associated, is a sea-water lake, apparently with sea-fauna still present.
The city was the administrative and religious heart of a pre-Incan civilisation that began in the year 237 BC and endured for over 1400 years.
During its peak (724- 1172 AD) the Tiahuanacan Empire covered nearly all of Bolivia, Northern Chile and Southern Peru, ruling over more than three million subjects.
Vice President Vctor Hugo Crdenas, elected in 1993, was the first indigenous person elected to this high office in South America.It now stands in the NW corner of the Kalasasaya, although it was found fallen and completely covered in mud elsewhere on the site.Roughly fifteen miles from Tiahuanaco, this lake is believed to have once extended to the city. Its present fauna (including a species of sea horse), a nearby salt-water lake, and the angle of an ancient shore-line have led scientists to consider that the lake may have once been attached to the sea, following which it was raised to its present height.Bennett who conducted the first archaeological research at Tiahuanaco in the 1930's, the Bennett Stela represents a human figure wearing elaborate clothes and a crown.The 10 ton Gateway of the Sun is monolithic, carved from a single block of Andesite granite, now broken right down the center.
Indications of man-made structures below the level of lake Titicaca (which is slowly drying up over time), suggests that our understanding of the site is far from complete.
