Extensive fossil evidence for transition to land animals.

[shunyadragon]

A number of different species of different sizes have been found for filling the gap for transitional animals between amphibians and land animals to resolve the problem called Romer's Gap.

Do you realize that paper is from 2002, almost 15 years old, and predates finds like Tiktaalik?

The original article was a more recent layman science article that covered the related fossils discovered since. I referred to this article in Nature referenced in the original article, because it gave a good scientific explanation of the discoveries of the fossils over the past 15 years related to these discoveries of transition fossils between amphibians and land animals.

When possible I will cite the best possible scientific article related to the layman's article in the news.

What original article?

OK but why didn't you post that to start with, and why did you post it twice now? Those senior moments happening more and more frequently are a pain, aren't they?

ETA: here's the whole paper cited by the article

A Diverse Tetrapod Fauna at the Base of 'Romer's Gap'

These are some pretty neat finds for sure.

The layman's article was not that good and I do not like to post layman's articles when Nature and PLOS are better. No problem with what is posted. If you have other articles please post them.

The extensive fossil evidence recently discovered filling Romer's Gap is the most important discoveries in the past 20 years. Recent discoveries in primate fossils of our ancestors is the other.

Have you heard of circulus vitiosus in probando?

The places (implicitly) labelled Devonian and Carboniferous here are so labelled because Devonian and Carboniferous fossils are found in them.

The fossils labelled Devonian and Carboniferous are so labelled because found in Devonian and Carboniferous places.

Are you familiar with absolute dating techniques that physicists developed quite awhile back?

Are you familiar with absolute dating techniques that physicists developed quite awhile back?

I have heard a few things about these, yes.

* Ka-Ar is totally unreliable with young samples (and on a YEC view all are).
* U-Pb and Th-Pb are unreliable as to excluding any Pb was along all the time + at least with U, decay rate can have been shortened due to radioactivity.
* Isochron dating, I really just rely on what CMI says, it is a bit over my head.
* A universe 13.5 or 13.7 billion light years in radius ultimately depends on trigonometry being applied on ... so called "annual stellar parallax".

A thing which a geocentric need not accept:

I have also heard, most finds are dated by one or two, and in cases of conflict, which occur, it is often the date least likely to disagree with the general theory of evolution which is accepted, the other one silently discarded.

More to the point here:

No reference to any dating technique beyond biostratigraphy being used.

The section methods only discusses methods of phylogenetic inclusion, not method of dating used at Inverclyde Group of Ballagan Formation or Auchenreoch Glen.

But why don't you ask [email protected] what dating methods he used?

So that's a "no", then. You are unfamiliar with the absolute dating techniques used.

I hope you won't object if those of us who do understand them ignore anything you have to say an the topic (other than as a source of amusement).
