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

Any more wilful trolling posts in this thread and I make a formal complaint.

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.

...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.

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).

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.

All ancient life - however humble is interesting.

'Intelligent' slime that suggests a primitive form of learning may predate the emergence of nervous systems, the evolutionary origins of dreams and will it ever be possible to clone a non-avian dinosaur from ancient DNA?

The short answer is no.
