Ancient Life

They are becoming aggressive with the ads. I have downloaded Brave to avoid ads but quit using it when Google gave me flak about getting into their sites, such as my blog. So I suffer the ads.

Hyracotherium is the "fashionable name for eohippus . Blme the Europeans even though they inherited horses and we di all the work.

Im not sure of the climate peaks but during the "Grand Coupure" (I think thats how itwas spelt) , a time to the late oligocene, all the areas of the world bgan cooling . The shallow sea in the mid US bcame a great grasslan and grasslands all over were associated with a mass extinction (the " bigass breakage" which sounds better in french), and all the paleo forms of animals died out and their neer forms began rising.
Horses were tied pretty much to the evironment because as the grasslands appeared , theMesotherial toes (3 hooflets) became vestigial , as did the limb patterns of the ancient paleocetaceans. From the end of the Oligocene the estuarine areas along the sothern
Indo -African areas where whale evolution began, became deeper water areas with very few remaining estuaries that originally gave rise to the packycetus and ambliocetus. The beginning of the Miocene saw the appearances of many modern form species, and a big hiatus in species of earlier "asian" types .

During these times two bolides were discovered in the stratigraphy within the last 25 years.

The first, the Chesapeake "Invader" was discovered by dr Wiley Poag of USGS from data he couldnt understand from UGS ground water monitoring systems. Wells drilled within the areas of the Potomac and Rappahannock and James Rivers showed weird water levels, as if all these areas were part of a single aquifer zone. Also the chemistry of the water was indicative of some extra aquifer metallic ions.later drilling showed the typical layers of shocked quartz and really smashed up deep zones of paleocene and Cretaceous underlying rocks.
Then another one was found in the Siberian rocks of the Creatceous. This was called the Popagai bolide. It was apparently a final smack that marched the climate to a cooler, lower marine water stand . So the "little extinction event" was an opportunity for newer forms of species to develop and become "overadapted" to a new environmental system

This video is slightly misleading but he corrects it at the end

good deal. Theres a few on here that like to argue the "direct lineage" argument that they acquired more from SCi Fi comic books than from working fossil guys.

Heres a quiz

What do THANITOTHERISTES degrootosum and Poutine have in common?

Your search - THANITOTHERISTES degrootosum - did not match any documents.

Suggestions:

Make sure all words are spelled correctly.
Try different keywords.
Try more general keywords.
Try fewer keywords.

So I'm guessing both are laden with cheese.

I am a Pan Troglodyte I dunno! Did you say Putin? What was the other species?
My search engine wants me to think I don wanna!

just try thanitorestes. forget the degrootum(ensis?)

Okay -
Dum de dum -

sorry. I was sent a thingy from a friend who said it was th neest discovery of the "Reaper of Death"

THANATOTHERISTES degrootorum.
I wa kinda off on my spelling eh?

Ah. I saw the headline on that and planned to go back and read.

I would say its bacteria. Scientists are talking of the permafrost melting and releasing microscopic creatures. Perhaps this might be interesting: http://www.bbc.com/earth/story/20160602-some-lifeforms-may-have-been-alive-since-the-dinosaur-era

Research on soldier ants reveals that evolution can go in reverse
https://phys.org/news/2020-03-soldier-ants-reveals-evolution-reverse.html

excellent post wdgar. Its been a bit of fossil weirdness that of the trilobite clan, the ntire family of these critters had seemed to return to a simple form of T bites in the "end days" of all trilobite species just before they went all wxtinct.
Prmian Trilobites began to look like early " 45 slug" shape pf late Cambrian ones. There was a pwriod of waay increased spines and "tail fins" (thats what they look like to me) and then, just before thy blinkd out in "The Big Dying" , they lookd like they returned toa simpl generalized shape .

Thi kinda refutes "Dollo's Law" (which I hated as a law because it had no equations)

I’ve been trying to tell you for years now - The only evolution actually observed, is loss of function, ie, 'Backwards Evolution'. Order to disorder. Entropy.

REALLY? You see everything as entropy? Please explain the adaptation in galapagos finches specific to two islands(And studied by the Princeton ethologists husband and wife team Drs Grant and Grant since the 1960's and who've published several tens of papers an two books on the subject). On these islands were several immigrant species that had adapted to handle a specific dietary change from their original homes on the SA mainland.

Oh yeh, how about cichlid fishes that had been held behind constructed dams on the Connecticut River back in early colonial times. Many of these cichlids had , via adaptive evolution, completely changed their dietary preferences and consequently, their shapes.
