Source of the massive extinction of species in the late Cretaceous
They claim clear evidence that it was not the Deccan Traps but a meteor.
We will see. These things can be refuted for years.

I saw the article above and laughed. It reminded me of this TV psuedo doc, Great Lakes Copper Heist.
The premise was that since copper was mined by First Nations peoples they were trading it to ancient Greeks, who were rowing across the Atlantic and into the Great Lakes for it. Natives were not marketable enough so they used a racist fiction to try to sell it. They have the balls to call it the History Channel. LOL
Cougar Origins
Cougars (Puma concolor) Control Feral Horse (Equus caballus) Populations in Some Environments
“Incidentally, the Pleistocene cougars that lived in North America were not directly ancestral to cougars that live on this continent now. They were an extinct ecomorph that grew slightly larger than modern cougars and may have had spotted fur. According to genetic evidence, all modern North American cougars descend from a population originating in eastern South America about 10,000 years ago. Strange as it may seem, this population completely replaced the Pleistocene ecomorph.”
The interesting bit.
Life-sized camel carvings

“the data indicates that the sculptures were made with stone tools during the 6th millennium BCE.”
The camel thing is interesting as is this superb giraffe rock art. From facebook but I forget the context . West african? Ancient?
DNA Advances
This technique is about a hundred times faster than current state-of-the-art approaches and uses one-fifth the resources.
Scientists are vacuuming eDNA from the air
Analyzing DNA in soil could be an effective way of tracking animals
I quess, you could see these coming but it is still remarkable. It reminds me of Gattaca, the sci fi movie, where DNA is used for oppression, etc.
Ranch Land Eco Innovations
Pic for attention.
A really good update on it.
Despite the title, not much to do with bison.
FLAMINGO ART
FLAMINGO ART
Giant flamingo sculpture coming to Tampa International Airport in the Spring of 2022 based on an actual underwater picture of a foraging flamingo.
A lot of public art leaves me unimpressed but this is a cool idea. I love the water dappled light on the floor.
some serious protein
10 million more than expected. That is some serious protein.
Compared to our empty rivers here it is a miracle.
“Just because the habitat doesn’t have fish in it now doesn’t mean it’s not holding the potential for fish in the future.”
The big take away and hope.
A good piece.
Fly Fishing Movie, not that one a new one
How good? I am not hopeful but we will see.
