K/Pg Boundary Event

Geological chronology is at the heart of a division in earth sciences - between those that favour an asteroid impact and those that, instead, blame the Deccan Traps for the demise of the dinosaurs (and various other life forms). The Traps is a large eruption of lava in what is now India. At ... we have more on the disupte which could easily be resolved if geologists accepted sediments can be laid down quickly on occasion.

T Rex and Shark Teeth

Robert  also sent in a link to ... which claims fossils of Tyrannosaurus Rex have been found in the same geological sediments as sharks teeth. How can that happen. It is explained away by mainstream by saying these are freshwater sharks living in a vast inland sea in N America. The author of this piece claims the teeth are exactly the same as its modern equivalent - living in the salt oceans. Is this smoke and mirrors. A sort of 'nothing to see here, move on' moment so beloved by the establishment.

More Dinosaur Tracks

More dinosaur tracks. This time in Queensland, Australia - see ... it is described as a well travelled dinosaur trackway. A variety of dinosaur footprints is represented - sauropods for example, as one might expect, but also theropods and ornithopods. The biggest sequence of sauropod footprints can be traced for a distance of 40m (some two dozen separate footprints). These are now all in the local museum ...


William sent in this link to ... which concerns the Italian island of Stromboli. It is in fact a volcano and has been periodically active since 1932 - but not on a grand scale. In the fairly recent past it has been more active - which seems to have caused the flanks of the volcano to collapse into the sea causing at least one major tsunami event to strike Naples. One of the ocassions was back in the 14th century AD - and the marine storm struck Naples in 1343.

Unusual Fossil

At ... soft bodied species such as spiders aren't usually fossilised in rock like animals with bones and teeth. More often than not fossil insects are found encased in amber. However, fossil spiders found in Korean shale (the Lower Cretaceous Jinju Formation) are remarkable as they feature reflective eyes that enabled them to hunt at night - fossilised. They were preserved in strange silvery flecks on dark rock, their large eyes marked with crescentic features.

High Sea Levels 6000 Years Ago

This information is derived from a study, Oliver and Terry 2019, published in Palaeogeography, Palaeoclimatology and Palaeoecology (see ... ). Basically, oyster evidence affirm that sea levels were up to 3.8m higher (in Thailand) 6000 years ago (roughly around 4000BC).

Oyster remains have been found encrusted in rocks 2.5 to 3.8m above the present mean sea level (a series of stranded shore lines).

Ice Age Animal Trove

Douglas Palmer reports in Down to Earth 106 (February 2019) the discovery of mammoth and rhinoceros remains in Cambridgeshire - during road works upgrading the A14 between Cambridge and Huntingdon. While excavating gravel from a pit near Fenstanton digger driver Darren Hickman found a mammoth tusk and the ice age bones ... in the base clay area. Present amongst the bones, including  skulls were woolly rhinoceros (adapted to the cold) along with rhinoceros usually found in warmer climes.

Panama Geology Again

Loks like a case of a dog with a bone. At ... mainstream don't seem to want to abandon their cherished views on North America crashing into South America - but some geologists are being stubborn. This is another story about the isthmus of Panama. How did it come into being. In a study in Scientific Reports we are told that not only were tectonic process involved but volcanoes also played a significant role. Mainstream opinion is that it formed 2.8 million years ago as the Caribbean plate bumped into the South American plate.

Veins of Gold

At ... earthquakes make veins of gold in an instant. Pressure changes can cause precious metals to form when the crust moves. Geologists have long known veins of gold are formed by mineral deposition from hot fluids flowing through cracks deep below the surfacve. A study in Nature Geoscience has found the process can occur virtually in an instant - even within a fraction of a second.

Scottish Volcanoes and Dinosaur Footprints

At ... around 56 million years ago (give or take the odd day) global temperatures spiked. In the UK this coincided with a massive eruption on what is now the Isle of Skye - the Cuillins. See Scientific Reports (January of 2019). Geologically, this is close to the boundary between the Paleocene and the Eocene. Volcanic activity was also endemic on Greenland and elsewhere in the British Isles and the general North Sea region.
