At https://phys.org/news/2025-09-newly-dated-million-year-dinosaur.html … we have an interesting background story, in that the focus of the article is on the dating of some dinosaur eggs but the real story, lurking behind the screen, is on how those eggs came to be fossilised in the first instance. However, the dating itself is also revealing as it is firmly placed in the Late Cretaceous time zone. Qinglongshan in China contains three dinosaur egg caches containing around 3000 dinosaur eggs. They seem to have remained intact with minimal deformation – preserved for 85 million years in a virtually pristine condition. Locked in rock of course – embedded within breccia bearing silt stones. This seems to be a mixture of gravels and watery soil that solidified over time. Is this further evidence that some Cretaceous sediments were laid down quickly? The Late Cretaceous dates from roughly 100 to 66 million years ago on the geochronological time scale. Can that be compressed significantly?
We are also told that in the Cretaceous there is evidence the Earth was plagued by widespread volcanic activity, oceanic oxygen depletion, and mass extinctions. These are just the sort of things that might have occurred as a result of the asteroid strike at Chicxulub, and other locations, firmly fixed at the end of the Cretaceous. Why would such activity have broken out prior to the asteroid breaking up and striking several places in a global onslaught? This event is known to have caused huge surges in oceanic waters affecting landscapes on the peripheries of the Pacific as well as he Atlantic. Such as China.
We are also that in the Late Cretaceous the climate cooled. Presumably this could be interpreted as evidence of volcanic activity affecting the atmosphere and blocking sunlight. The question then is why is this dated prior to the asteroid strike. If those sediments laid down were contemporary with the space rock, or rocks, the above would make a lot more sense. After all, the Mount St Helens volcano laid down layers of sediment in a matter of hours and days. Localised of course, as opposed to globally at the time of the asteroid strike. As an aside, we are also informed there are other sites with fossilised dinosaur eggs in China. This suggests, one might think, a big splash event washed over a considerable area of what is now China. I find it peculiar that the Chinese who have no skin in the game of religious fundamentalism seem to keep on song with the mainstream mantra, which is the product of the backlash against Noachian ideas. Why don’t they look at things dispassionately rather than paying lip service to outdated paradigms? Possibly it is due to the wish to publish in western journals. What is being published in China itself on these matters?
