The purpose of such an elaborate structure remains a big open question
A jaw-dropping example of Ice Age architecture has been unearthed on Russia’s forest steppe: a huge, circular structure built with the bones of at least 60 woolly mammoths. But exactly why hunter-gatherers enduring the frigid realities of life 25,000 years ago would construct the 40-foot diameter building is a fascinating question.
“Clearly a lot of time and effort went into building this structure so it was obviously important to the people that made it for some reason,” says Alexander Pryor, an archaeologist at the University of Exeter (U.K.). He is the lead author of a new study published this week in the journal Antiquity describing the find at Kostenki, a place where many important Paleolithic sites lie clustered around the Don River.
Golden lion tamarins live in the rapidly diminishing Atlantic Forest, a richly biodiverse region
that stretches down through Brazil and into Argentina and Paraguay. The Reserva Biológica
Poço das Antas, a 28,000-acre (11,331-hectare) forest reserve near Rio de Janeiro, protects the
golden lion tamarin’s habitat.
Golden Lion Tamarin is a mammal that traditionally inhabits lowland tropical forest. It has a hair covering and is able to speed up to 40km/h (24mph). Golden Lion Tamarin (leontopithecus rosalia) usually is 20-33.5cm (13.2-8in) and weights 550-700g (19-25oz). The animal lives 8-15 years in a troop lifestyle. Eats mostly: fruit, insects, small mammals, small reptiles
JUST LOOK AT THE EXPRESSION ON MY FACE & LOOK INTO MY EYES &YOU SEE WHAT..??
Once upon a time, animals were absolutely enormous. As humans and other predators began to roam the earth, animals began to decrease from their once colossal sizes. Nowadays, you can find giant animals mostly on islands, where animals live in isolation from humans and their impact. They are able to grow to their full size thanks to a lack of predators and because they have greater access to more resources, like food and water. While you would expect animals this big to eat a lot of food, many of them actually eat the same amount of food as their regular size counterparts. Dinosaurs may no longer be in existence, but there are still some modern-day monsters, say you will, that are roaming our earth.
Two White Giraffes—A Mom and a Calf—Are Thrilling Wildlife Fans in Kenya
A mother and a calf were spotted by the Ishaqbini Hirola Conservancy in Garissa County, Kenya. The giraffes have leucism, a genetic condition that reduces the ability to produce pigment.
Unlike albinism, animals with leucism may display ghostly traces of their normal patterns
The Ishaqbini Hirola Conservancy in Garissa County, Kenya, is famous for its rare hirola antelopes: quick, sharp-horned ungulates endemic to the area. Back in early June, though, a resident walking near the conservancy saw something else unusual: a ghostly, tall animal, stepping through the brush.
The villager informed a ranger, who ferried the news to researchers at the nearby Hirola Conservation Program. “We hurriedly headed to the scene as soon as we got the news,” one researcher recalled recently, on the Program’s blog. “And lo! There, right [in front] of us, was the so hyped ‘white giraffe’ of Ishaqbini conservancy!” Just seconds later, another surprise was in store. There were not one, but two white giraffes: a mother and a calf.
As the researcher explains, these two giraffes have what is called leucism, a heritable genetic condition that reduces an animal’s ability to produce pigment. Unlike albinism, leucism doesn’t disrupt pigmentation entirely: affected individuals may display ghostly traces of their normal patterns. That’s true of the young giraffe in this video, whose spots remain slightly visible (he looks a bit like he’s just rolled around in flour).
Leucism has been noted in many different animal species, from pythons and crocodiles to lions and tigers. Although leucistic giraffes seem to be fairly rare, the wildlife biologist Zoe Muller writes that sightings have been reported as far back as 1938, and again in 1956, 2005, 2011, and 2015. (Muller points out that several of these leucistic giraffes were originally mischaracterized as albinos.)
In early 2016, camel herders in Garissa County started spotting another white giraffe, which researchers managed to photograph in April of that year. (It’s unclear whether this is the same giraffe as the mother with the calf.)
Since then, the HCP researcher writes, “sightings have become a common occurrence,” and community members are keeping their eyes peeled. “‘This is new to us,’ the researcher quotes a local ranger as saying. ‘I remember when I was a kid, we never saw them.’” Now, they have at least two to look out for.
