Just saw a story on the news about snow crab season being cancelled in Alaska. The fisheries reported than in less than 2 years ONE BILLION crabs have disappeared. There are virtually no crabs to be found and no one knows where they went or what happened. The theory that will be investigated is climate change and search parties will be sent to colder waters to look for them. Sadly hundreds of fisherman will not be able to make a living. Climate done changed people.

The myths that hint at past disasters (and The First Fossil Hunters)
Oxytropidoceras posted a topic in Fossil News
The myths that hint at past disasters, BBC Future By Mark Piesing, May 10, 2021 Yours, Paul H, -
I think this is a bait and switch article. It starts off by telling you about the Burgess shale then transitions into explaining why we are going extinct too. I didn't learn anything new from reading it though. Anyway there are pictures. Of trilobites. https://www.washingtonpost.com/outlook/2019/12/06/ghosts-future/?arc404=true

Meteor Impact Possible Special Harbinger Of Ice Age Mammals' Demise?
DD1991 posted a topic in Fossil News
A groundbreaking article that could provide a fresh new explanation for the extinction of the Ice Age megafauna...... http://www.theregister.co.uk/2013/09/03/canadian_comet_impact_fingered_for_triggering_younger_dryas_climate_shift/ With debate still ongoing over why the Ice Age mammals went extinct, the possible discovery of the remnants of an extraterrestrial object in Canada dating back 13,000 years ago may bolster the opinions of scientists who believe that the cavemen weren't totally responsible for the extinction of the imperial mammoths, the ground sloths, and the saber-toothed cats. If an extraterrestrial impact in Canada triggered climate change at the end of the Ice Age, then it may have been a Chicxulub moment for the wooly mammoths, the saber-toothed cats, and the ground sloths. -
Last year researchers published a paper suggesting that sauropod dinosaurs would have made a contribution to climate change in the Mesozoic by producing as much as 520 million tons of methane gas. However, little research has been done into the fossil sites where accumulations of coprolites are associated with sauropods proving that sauropods produced enough methane gas to warm the earth. Are there any fossil sites around the world where sauropod remains have been found in association with multiple coprolites? If so, then we might hypothesize that the biggest flatulence by sauropod dinosaurs may have been due to the fact that the sauropods that were physically exhausted after long migrations across barren landscapes may have consumed too much plant material. Note: If a Chinese gas company found a turiasaur skeleton in Xinjiang that is associated with coprolite pyramids, then that sauropod would be named Gasotitan (just as Gasosaurus was named because it was found by a Chinese gas company).

"rising Sea Level" Conference, Parrsboro, Nova Scotia - Oct. 19Th
redleaf101 posted a topic in Members' News & Diversions
Hi guys! Anybody on the East Coast, the Fundy Geological Museum in Parrsboro, Nova Scotia, is hosting a conference on "Rising Sea Level: The Impact on Coastal Communities along the Bay of Fundy", held this coming Friday October 19th. My friend Ken Adams, whom I've had the luck to accompany on many of his geological walks of the Cumburland area, had made past remarks on the ever changing landscape, the pace of erosion, and intriguing points. Here's the FGM's summary from their website: http://museum.gov.ns...conference.aspx Cheers! Keenan
