bison

At http://popular-archaeology.com/issue/spring-2016/article/archaeologists-... ... archaeologists have unearthed the bone of pre-Younger Dryas bison on a dig in Florida (among other interesting things) some ten feet below the ground surface. The bone was found in material from the Pleistocene epoch and it seems it is a rare find as bison roamed a grassland environment and most bones disintegrated over time.

monkey business

At http://archaeologynewsnetwork.blogspot.co.uk/2016/04/first-north-america... ... (see also www.smithsonianmag.com/smart-news/monkeys-may-have-floated-to-north-amer...) ... is one of those stories where a new find is like a torpedo, holing a consensus theory in the midriffs. Fossil teeth of monkeys have been unearthed by the Panama Canal expansion project. It was thought monkeys crossed over from South America when the two parts of the continent came together around 3.5 million years ago.

radiation a lesser effect than ...

Radiation appears to have a lesser effect on animals than human activity and interference - see http://phys.org/print380252676.html. Robert Farrar has also sent in the link to http://crev.info/2016/04/why-chernobyl-neighbors-are-not-dying/ ... and the same story can be seen at other online sites (now or in the recent past). We might begin by saying here we go again -Chernobyl and the exclusive zone. However, this time some further information is p[assed on to Joe Public. Some of the animals in the exclusion zone, such as Dzungarian horses, were deliberately introduced as an experiment.

radioactive pigs

At www.smithsonianmag.com/smart-news/radioactive-boars-rampage-around-fukus... ... following the meltdown of the Fukushima nuclear power station during the earthquake and tsunami wave the surrounding area was evacuated - leaving empty houses, sheds and outbuildings behind. These were duly colonised by animals - most notably by wild pigs. This may say a bit like 'Animal Farm' but the pigs really did get to upgrade to houses.

Life in Space

At http://phys.org/print379308179.html ... an interesting discovery. Ribose and related sugar molecules, the backbone of RNA, or ribonucleic acids, which are important in the coding of genetic information from before the emergence of DNA, is found in comets and asteroids. It may actually be abundant in the universe at large. As such, life beyond the confines of the Earth must be feasible.

Big Head

At www.yahoo.com/news/giant-mammoth-skull-discovered-bulldozer-operator-134... ... the skull of an Ice Age mammoth has been dug up by a bulldozer operator in Oklahoma. This is not your cold adapted mammoth covered in a woolly exterior but a species adapted to a temperate climate - or even perhaps a warm one. It is also much larger than woolly mammoths, males reaching up to three times the size. Surprisingly, it was found in a sand pit - see image below

soft tissue

Robert Farrar sent in this link, http://crev.info/2016/03/triassic-reptile-soft-tissue/ ... which concerns a paper in the online journal PLoS One which documents the survival of soft tissue preserved in ancient reptiles from the Triassic. Soft tissue from Jurassic dinosaurs is also known - but we are going back over 200 million years ago.

lizards in amber

Lots of insects have been found in amber - but apparently so were lizards and geekos ... and the chameleon - go to http://phys.org/print376555684.html

moose, dragonflies, owls

At http://phys.org/print376124193.html ... a moose living in western Siberia, in the Tomsk region, has been gene mapped in an attempt to form a link with moose living in Siberia until 30 to 40,000 years ago. They appear to have disappeared - or most of them - but so did lots of other animals at this point in time (and no doubt humans too).

At http://phys.org/print376129772.html ... the subject here is the Snowy Owl and a bird that was tagged and travelled to the far north and back to Maryland - stopping enroute on top of a skyscraper in Manhattan.

writhing innards

Writhing innards, as in wiggly things like nematoid worms and squidgy life forms such as bacteria. At www.smithsonianmag.com/science-nature/inner-earth-teeming-exotic-forms-l... ... we learn a mile to two miles below the surface of our planet life is teeming with diverse creatures. Geomicrobiologists have been exploring the ground under our feet - looking at rocks and strata that go back even earlier than the Jurassic. Bacteria are still living in them. Deep life has been found all over the world under a variety of conditions.
