I'm not happy with the tree. Nowhere does it mention what Thalattosauria includes, and the genera it includes
for it and for Sauropterygia make it impossible for me to tell in which clade plesiosaurs belong.

I could tell from the silhouette into which group Placodus goes, and ironically, it is the only
listed genus among the two groups whose name I recognized.

So, to work out what belongs with which sub-clade is an arduous process.
It's a tree for specialists in the paleontology of amniotes, catering to nobody else
except amateurs whose main interest is the early sauropsids and synapsids.

I'm pretty sure your happiness was not a factor the authors took into account. Still, the phylogenetics of early
Synapsids and Sauropsids is a very active area in current paleonlotogy, not "catering to nobody else except
amateurs". If working out the details is arduous, well, that's the way it goes. I'd have thought you might have
been interested in the discussion of the difficulties in placement of turtles, and the increasing agreement of
morphological vs. genetic analysis.

I note that, though the text doesn't mention it, the tree makes
sauropterygians into archosauromorphs, when if I recall they have
previously been considered more closely related to lepidosaurs.

Yes. There are a bunch of surprises in there. Follow up research should be
interesting.

You need some newer references. Thalattosaurs are a distinctive group;
they're mentioned by Romer 1966 in the chapter on lepidosaurs, and never
associated with plesiosaurs to my knowledge. Sauropterygia is a
well-known taxon that includes plesiosaurs, placodonts, and a few
others; they're also in Romer 1966. in the chapter on euryapsids.

You are changing the subject from the paper to something that is such a no-brainer,
even Glenn would probably agree with it, and cherry-picking words of mine into a context
where you know they don't belong.

When a mountain labors and brings out a mouse of a tree that caters to perhaps
less than 100 people in the whole world, it reflects no credit on the mountain
that it labored long and arduously.

And the text is hardly better. I did a word search for Thalattosauria and Sauropterygia, and
nowhere does it mention ANY of the genera either group includes.

Worse yet, when I started a word search for "plesiosaur" it stopped at "plesi" with one hit,
an article that falls under "Recommended reading." Not even a footnote or endnote or reference.

Ancient history. What *new* difficulties did they bring up?

Of turtles, and what else that wasn't already agreed on in Carroll's 1988 text?

Genetic analysis can't touch long extinct species.
All Sauropterygians died out before the Cenozoic, and
all Thalattosaurs during the Triassic.

Thus, moving placodonts from Diapsida Incertae Sedis [Carroll, 1988]
to Sauropterygia had NOTHING to do with the "increasing agreement".

Ichthyosaurs are another group that has been put into archosauromorphs.
Wasn't that a surprise for you too?

Of course, none of these placements has anything to do with the "increasing agreement"
of which Erik made so much.

By the way, I have another criticism of Fig. 1. It should have been supplemented
with another tree that didn't concern itself with divergence times but just made
it easy to see what the individual clades are. I had a dickens of a time making sure
turtles weren't archosauromorphs but were archelosaurs according to the tree.

From "not happy" to "happiness"...LOL! In a very real way, authors of scientific papers should be concerned with whether others are satisfied with their assumptions and results. That should not be restricted to a select group of "others". That Erik wants you to believe they aren't concerned says volumes about Erik, and not a peep about the authors themselves.
Arrogance doesn't necessarily indicate a conscious motive to troll, but regardless...it is ironic, and quite curious, that the result is the same, and that arrogant people often do not see that.

I called attention to what I regard as an interesting article. No flamebait. You don't
seem interested, and raised objections. In the past you did show great interest in
the phylogenitic placement of turtles, making much of the difference between trees
constructed using morphology alone, or molecular phylogeny. This paper addresses that.
No trolling intended. If you think they all wrong, fine. I'm not arguing with you.

It would have been if I had noticed, but I was concentrating on
Sauropterygia.

I had no trouble reading the tree. And of course Science likes to cut
space to the bone, so two versions of the same tree would be very
unlikely to make it into the paper.

Transparently disingenous (= more flamebait). I said that because of what you
said this time around, not about the OP:

That shows I AM interested. And now that I've read more of it, I have changed
my overall opinion of it. If you want to know how, clean up your act.

I asked you a question about that above, which you are ignoring. Can you find it and answer it?

To make it easy for you, I improved on the text to which you bottom-posted
by putting in spacing before and after the question. Google keeps ignoring spacing
between lines of text which it is hiding.

> No trolling intended.

If you are sincere, you must offend a lot of people without realizing it.

> If you think they all wrong, fine. I'm not arguing with you.

More flamebait.

If you want to talk about the substance of the paper, great; I'll participate. I'm NOT going
to delve into your previous posts to look for your question. If it's important, just ask.

I'm also not "flamebaiting" you, whatever you perceive, not will I argue about that. If we
stick to paleo, good. Otherwise, I'm gone.

Erik breezed by this PS as though it weren't there, and in his latest reply
he gave the pathetic excuse that he doesn't read my longer posts "to the end, or not at all".
But his earlier reply (to the same post to which you are replying here) started IMMEDIATELY below the PS.

> From "not happy" to "happiness"...LOL! In a very real way, authors of scientific papers should be concerned with whether others are satisfied with their assumptions and results.

More relevantly, concerned about the way they try to make things easy for people outside their specialty.
To the caption of their huge, elaborate tree, they could easily have added that Thalattosauria
is a small group that has been scantily studied up to now, while Sauropterygia includes the
well-known plesiosaurs.

> That should not be restricted to a select group of "others". That Erik wants you to believe they aren't concerned says volumes about Erik, and not a peep about the authors themselves.

> Arrogance doesn't necessarily indicate a conscious motive to troll, but regardless...it is ironic, and quite curious, that the result is the same, and that arrogant people often do not see that.

Erik has crossed swords enough with me over the last (FULL, I believe) decade that he
has no excuse for not seeing it in hindsight, at least. That's why I kept holding his feet
to the fire on this thread.

Anyway, in a few minutes, I will be replying to his latest post, where I will be changing
the accusations from "flamebait" to "trolling," which doesn't imply such specific conscious intent.

You never answered this question, Erik, probably because the correct

I'm changing the "flamebait" accusation to the more general one of trolling [see below for my definition]
because I can't document your hopes, and your "reply" to my accusation named something innocuous
that you did, followed by transferring the "denial" to *it*.

What is your definition of trolling, Erik?

Mine is making provocative statements that lack integrity -- in your case,
copious highly disingenuous statements -- which you make no effort to justify
when called out on it.

I called you out on one of them in my next comment, which you ignored:

I may have misread your intent, so I am modifying the accusation to "More trolling."

And here you are, doing more trolling [keyword: "delve"] that you make no effort to justify
after I called out on it:

That's another form of trolling.

You showed no inclination to stick to it, despite my invitation below.

Jillery should be delighted to see you are (unwittingly, perhaps) working the opposite side of
the street from herself and Zen Cycle, which they worked to the hilt over in talk.origins:

https://groups.google.com/g/talk.origins/c/uMOdTD1NL8A/m/pN6QVZE-BwAJ
Re: Bad Form, Peter
small excerpt:
It's been a strategy of jillery's since at least as far back as 2014. One of her favorite tactics
over the years has been to say, "Right here would have been a good place to..."
when any responsible person would say "be" instead of "have been" under the circumstances.

I've told her time and again how intellectually dishonest this tactic was,
that she was goading me into doing 1,000 line posts which no one would read.
The reason was that if I were to try to anticipate ALL questions about
and ALL objections to what I write, I'd be stuck in a "turtles all the way down"
type situation, explaining my explanations of explanations...
[end of excerpt]

> The repeated material above is a case in point.

I believe you would be delighted to see how flagrantly jillery and Zen Cycle were working the opposite side
of the street from your workings here, if you could bring yourself to read the whole post I've linked.

True, I do not find such mild condescension insulting.

You brought the paper to our attention, so you might have had some surprises in
mind that nobody else might have thought of. So "them" is begging the question,
as well as declining my invitation [see above].

Reviewing this thread as part of a recent discussion/debate on the "False Dichotomy..." thread,
I noticed that there were a couple of loose ends on it.

Both were surprises for me; I hadn't even been aware of ichthyosaurs being
in the sauropsid crown group. Were you?

Carroll (1988) hadn't placed either them or the sauropterygians inside
what we now consider to be the crown group:
"The placodonts appear to be derived from among early diapsids, but we cannot be more specific about their ancestry at present. Nothosaurs and plesiosaurs are united by unique features of the skull and shoulder girdle that support their inclusion in a distinct order, Sauropterygia, which may be a sister group of the lepidosaurs." [p. 241]

Benton (2005) third edition has the placodonts in a clade with sauropterigians on Fig.6.6, p. 150,
with lepdidosauroformes as the sister group, but ichthyosaurs are outside the sauropsid crown group.

The only increasing agreement, at least according to the article Erik linked, was in
the placement of turtles, where previously the morphological evidence was
at odds with the molecular. Carroll, relying only on the morphological, placed
turtles outside Diapsida. Ironically, this resulted in sauropterytgians being inside
the sauropsid crown group, for an entirely different reason than this article has them.

This was the only hard part for me. The twofold division above is extremely tall
and extremely thin, crammed into the "G" portion of the Permian.

What with all the nodes labeled with dates, it would have been child's play
to expand the "G" portion of the tree two or threefold with a little note at the
bottom about that.

Yes. Most people who put sauropterygians outside the squamate +
archosaur node also put turtles as primitively anapsid, and so included
all sorts of things in the sauropsid crown group.

It seems to me that ichthyosaurs have traditionally been considered
"euryapsids", with turtles as "anapsids" outside the group. Then again,
I can't recall whether they were also outside sauroposids, maybe even
outside synapsids + other groups with holes in the head.

Where did Benton put turtles?

Exactly.

Science doesn't usually mess with the authors' figures except to correct
factual errors, if they even do that. And to cut them for reasons of
space. And reviewers seldom go into issues of graphic clarity. Such is
the process.
