Styracosaurus

At https://archaeologynewsnetwork.blogspot.com/2019/11/dinosaur-skull-turns... ... a dinosaur skull unearthed in 2015 is causing a problem. It was the skull of a styracosaurus, complete with horns. The differences in the skull's left and right profiles are so extreme they appear to belong to two different animals - but clearly aren't ...

Sugars in Meteorites

This story is at https://phys.org/news/2019-11-sugars-meteorites-clues-life.html ... virtually anything organic in comets and meteors is deemed to be a clue to the origin of life - without many clues on how they convert from primitive building blocks into actual building blocks. Research continues and more information is popping up all the time. Here we have an international team that say that sugars found in a couple of meteorites support the hypothesis that chemical reactions in asteroids, their parent bodies, can make sense of life's ingredients. Not everything though.

Dinosaur Finds

At https://phys.org/news/2019-11-oldest-carnivorous-dinosaur-fossil-unearth... ... the oldest carnivorous dinosaur found to date has been unearthed in Brazil. It has been dated 233 million years ago -during the Triassic. At this time South America was still part of Pangeae (joined at the hip with Africa). The fossil was intact (see image below). Fossil evidence of Triassic dinosaurs are apparently scarce but see also https://doi.org/10.7717/peerj.7903

The Dinosaur Trots

At https://archaeologynewsnetwork.blogspot.com/2019/10/jurassic-dinosaurs-t... ... Jurassic dinosaurs trotted between Europe and Africa. Dinosaur footprints in Europe and Morocco bear similarities which suggests either the two continents were closer or a shallow sea separated them.

  

One for the Kiddiewinks

Young children, especially small boys, are fascinated by the likes of Tyrannosaurus Rex and here we have a new species of giant predatory dinosaur found in Thailand - the Siamraptor .. go to https://archaeologynewsnetwork.blogspot.com/2019/10/meet-siamraptor-suwa... ...

Coral Reefs in central Europe

Back in the day, the Jurassic perioid no less, central Europe was covered by a shallow sea - the so called Tethys Sea. A study in the Zoological Journal of the Linnean Society (September 2019) describes a rich reef teeming with animals - fish, crabs, sea urchins, snails, clams, and oysters. They also include ammonites (squid with external shells) but the focus of the piece is on squat lobsters (which are lobsters that look like crabs, and are much smaller).

Marsupial Panda

At https://archaeologynewsnetwork.blogspot.com/2019/09/new-flying-reptile-s... ... a new species of pterosaur is among the largest ever flying animals according to a new study from Queen Mary University in London. Its remains were found in Alberta some 30 years ago but paleontologists, at the time, bracketed it with other known species of pterosaur.

Well I Never

In the evolutionary model of human development the Lower Palaeolithic humans (such as Homo erectus), responsible for the Acheulian stone tool assemblage, mostly hand axes and cleavers, are generally considered as primitive - and more primitive than the Middle Palaeolithic (Neanderthal/ Denisovan etc) and many streets more primitive than Upper Palaeolithic modern humans.

Giant Parrot

New Zealand is known for some unusual birds, from flightless (such as the kiwi) to over large (such as the Moa). It once harboured giant geese and a giant eagle. Now, it has a giant parrot - see https://archaeologynewsnetwork.blogspot.com/2019/08/meet-herculesthe-gia... ... the fossil remains are said to go back 19 million years - to the Miocene period. In fact, the site has offered up a rich assemblage of fossil birds. One may wonder how birds come to be fossilised intach and buried in the earth. Why don't they just fly away.

Fossil Forest China

Gary sent in the link to www.independent.co.uk/news/world/asia/fossil-forest-asia-devonian-period... ... the oldest fossil forest in Asia (or the oldest until an older one is uncovered). It goes back to a remote geological period, the Devonian. It was discovered in the walls of a clay quarry in China and is made up of 250,000 square meteres of fossilised lycopsid trees. Other Devonian forests are known from North America and Norway. See https://doi.org/10.1016/j.cub.2019.06.053
