Remember the Hobbits......the diminutive hominids found in Indonesia in 2003. The discovery caused a bit of a sensation as the fossils were dated at around 12,000 years old which would have leant a long period of co-existence with modern humans
Well.......the dates have now been revised to 50,000 years old which coincidentally (or not) puts it at around the time that modern humans arrived in the area http://www.bbc.co.uk/news/science-environment-35930979 |

The Bible teaches that God created the world around 6000 years ago, so the fossils can be no older than that.
In other news, it's ancient arachnid time: Scientists say a 305 million-year-old fossil is the closest relative to "true spiders" ever discovered - but is not itself a spider. Easily pre-dating the dinosaurs, the 1.5cm creature lived alongside the oldest known ancestors of modern spiders but its lineage is now extinct. |

A 10 million year old fossil snake (remarkably) reveals it's true colours.

Is it a bird?
Is it a plane? It's a very nice infographic on the massive pseudo-toothed marine bird Pelagornis sandersi (just click to enlarge). ![]() http://www.scientificamerican.com/bl...EFD_source.jpg |

Marching dinosaurs animated size comparison - make sure to click on 'more' to see the species shown (from the smallest to the real giants).
I was very impressed with this video and the bloke obviously took a lot of time and effort to create it. I find it really compelling. ![]() https://www.youtube.com/watch?v=rRiecAmGWHU |

...and now for a really weird swimmy, scorpiony thingy that's 430 million years old:
Bizarre fossil hauled its offspring around 'like kites'. A 430 million-year-old sea creature apparently dragged its offspring around on strings like kites - a baffling habit not seen anywhere else in the animal kingdom. |

The devastating consequences of the massive asteroid that smashed into the earth and wiped out the non-avian dinosaurs (some birds survived of course).
How strange to think that we (and the rest of the big mammals) owe our very existence to a random hammer blow from space. http://www.bbc.com/earth/story/20160...steroid-struck |

The evolutionary origins of laughter, what the ideal body size is for a foraging predatory dinosaur to scavenge most efficiently, why fish don't have necks and more on the Caenagnathid Apatoraptor pennatus.

A few more articles on the baby Titanosaur Rapetosaurus.
http://www.macalester.edu/news/2016/...baby-dinosaur/ http://news.nationalgeographic.com/2...l-independent/ A massive new raptorial sperm whale has been discovered from Australian waters (the tooth looks very similar to Livyatan melvillei and is slightly smaller than that species so the 18 metre estimate is probably exaggerated as Livyatan itself has been estimated at between 13.5 and 17.5 metres long). http://www.earthtouchnews.com/discov...th-to-prove-it http://www.inquisitr.com/3021695/5-m...-the-americas/ Finally - just how many species of mammoth were there In North America? https://backyardpaleo.wordpress.com/...many-mammoths/ |

The remarkable discovery of the almost complete skull of the Titanosaur Sarmientosaurus musacchioi which shows just how superb even the mighty sauropod's senses were.

In terms of visual appearance, this fossil is probably going to be the most boring ever but it is nevertheless significant in its own way:
A load of old rot”: fossil of oldest known land-dweller identified. The earliest example of an organism living on land – an early type of fungus – has been identified. The organism, from 440 million years ago, likely kick-started the process of rot and soil formation, which encouraged the later growth and diversification of life on land. |

Evidence that our ancestors were preyed upon by hyenas, a Mexican Centrosaurine and an Alaskan Therizinosaur.

A new species of the famous Whorl-Toothed 'shark' Helicoprion (actually a giant chimaera/ratfish) that may have exceeded 12 metres in length - making it the largest animal of it's day and one of the most formidable predators of all time.
http://www.eartharchives.org/article...-ancient-seas/ Another excellent article from Mark Witton - this time on the pterosaur Rhamphorhynchus muensteri. http://markwitton-com.blogspot.co.uk...-reptiles.html |
