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

Sahara Dust

Gary also sent in a link to www.newscientist.com/article/2211699-the-amazon-rainforest-depends-on-fi... ... it seems the Amazon rainforest gets most of its phosphorous from cooking fires and landscape fires in Africa, via dust whipped up from the Sahara desert and wafted across the Atlantic. How it got its phosphorous, a vital nutrient, when the Sahara was a green and wet landscape 10,000 to 5,000 years ago, is left unmentioned.

Dinosaur Burial Ground

At www.yahoo.com/entertainment/giant-dinosaur-bone-found-southwestern-19262... ... link sent in by William. The thigh bone of a massive dinosaur, probably a sauropod, was dug up by French paleontologists in SW France. See image below

   ... Sauropods lived during the Late Jurassic era and weighed up to 50 tonnes. Some 7500 fossils of 40 different species have been excavated at the site near Cognac (since 2010).
