An extraordinary fossil captures the struggle for existence during the Mesozoic.
Abstract
Dinosaurs and mammals have coexisted for the last ~230 million years.
Both groups arose during the Late Triassic and diversified throughout
the Mesozoic and into the Cenozoic (the latter in the form of birds). Although they undoubtedly interacted in many ways, direct fossil
evidence for their interaction is rare. Here we report a new fossil
find from the Lujiatun Member of the Lower Cretaceous Yixian Formation
of China, showing a gobiconodontid mammal and psittacosaurid dinosaur
locked in mortal combat. We entertain various hypothesized
explanations for this association, but the balance of the evidence
suggests that it represents a predation attempt on the part of the
smaller mammal, suddenly interrupted by, and preserved within, a
lahar-type volcanic debris flow. Mesozoic mammals are usually depicted
as having lived in the shadows of their larger dinosaurian
contemporaries, but this new fossil convincingly demonstrates that
mammals could pose a threat even to near fully-grown dinosaurs. The
Yixian Formation—and the Chinese fossil Jehol Biota more broadly—have played a particularly important role in revealing the diversity of small-bodied dinosaurs and other fauna. We anticipate that the
volcanically derived obrution deposits specific to the Lujiatun Member
will likewise continue to yield evidence for biotic interactions
otherwise unknown from the rest of the fossil record.

I celebrate the dominance of Repenomamus by predating on dinosaurs
whenever possible, preferably anatids.

You've got a problem with duck-billed dinosaurs?

No need for impersonation. The real John Harshman is a smart alec.I know that, but you are behaving like a smart alec aged 8 years old or less.

If so, then I withdraw the claim of "8 years or less". Otherwise, I ask whether

their study organisms. My sympathy to paleontologists.
Are you really John Harshman, or a smart alec impersonating him?
No need for impersonation. The real John Harshman is a smart alec.I know that, but you are behaving like a smart alec aged 8 years old or less.
Is your "sympathy" based on having eaten a good chunk of tinamou meat? Tinamous are the focal point
of your one claim to fame, a paper in PNAS co-authored with 18 (or is it 19?) biologists.
If so, then I withdraw the claim of "8 years or less". Otherwise, I ask whether
your role was that of someone putting together reams of data into a phylogenetic analysis, and if so, did you eat some part of those reams?
There are precedents. A while back, there was a talk.origins regular who called himself Steady Eddie. Then he disappeared, but seemingly returned a few years later. The impostor gave himself away by using foul language that Eddie wouldn't have dreamed of using.
I have no such suspicions about Pandora. I think she was just humoring your first remark.
In other words, she has a sense of humor, which you unfortunately lack.You have never tried to explain that perennial canard of yours.
You certainly haven't shown any support for it here; quite the contrary.
You've got to be kidding.

No, I am not. The only "support" I have ever seen is endless repetition

I'm sorry you had to be exposed to this kind of back and forth so soon, John. But it does give you some idea of what a hornet's nest s.b.p. is,
and talk.origins is much worse yet, because the number of dishonest, hypocritical
posters there is about ten times as big as it is here, and it extends to on-topic debates as well.
By the way, I had a real "et tu, Brute" moment during the 2018 unraveling of our mid-2015 agreement, described in the reply I did to Harshman
about half an hour ago.
However, I am a big one for letting bygones be bygones, and as long
as "Brutus" remains honest and sincere, I won't hold this behavior against him.
Or maybe I ask too much.
There is on-topic discussion on other threads here. I started a book review yesterday, and Pandora started the discussion. Later today I will continue both the book review and the discussion on the same thread.

You do not deny having lied in that way; a prudent course of action,

I gave that advice to John Kerr-Mudd, a newcomer to both talk.origins
and sci.bio.paleontology. It is an excellent policy for anyone who
hasn't had many months of observation in talk.origins as to who is guilty
of dishonest behavior in interpersonal conflicts, and who is
honest and sincere, even in the midst of these conflicts.
I neglected to mention that the same
advice applies to newcomers here.
The reason is that you and erik simpson destroyed an agreement
we had between us back in mid-2015 to treat sci.bio.paleontology
like an embassy where we lay aside our personal grievances
[understood: the ones raging in talk.origins at the time]
and treat each other like the best of ambassadors.
The agreement lasted until early 2018, when erik refused
to apologize for a serious breach he had made in that
agreement right about when I went on a long posting break
in December 2017. Not only that, but he then gave a totally
different standard for his own behavior, and you backed him
all the way.
An accomplice of his who disappeared about a year and a half ago also backed him,
then helped him to continue in his dishonest, hypocritical ways.
When his accomplice crossed over a particularly sacrosanct line,
I boycotted their posts for the rest of 2019.
You, Harshman, raised a big stink about me doing that,
but I held firm, for several good reasons.

Your response blithely ignores that last line.
You've got to be kidding.
No, I am not. The only "support" I have ever seen is endless repetition >>> of the canard, with no attempt to explain why what I write fits it.
Harshman even excused himself from an explanation in his own reply,
and lied that everyone knows it.
You do not deny having lied in that way; a prudent course of action,
since you haven't got a leg to stand on. However, you cast
prudence to the winds below.
Sorry. I deny having lied that way. Shouldn't have to tell you.
And now there will be an endless series of back and forth attacks
resulting from this irrelevant seed.
You are guilty below of a dirty debating tactic which I call The One Shade of Gray Meltdown.
This consists of seizing on one or two things two disparate things have in common,
and pretending there is little or no difference between them.
So this is your way of avoiding becoming embroiled in interpersonal
conflicts?
I gave that advice to John Kerr-Mudd, a newcomer to both talk.origins
and sci.bio.paleontology. It is an excellent policy for anyone who
hasn't had many months of observation in talk.origins as to who is guilty of dishonest behavior in interpersonal conflicts, and who is
honest and sincere, even in the midst of these conflicts.
I neglected to mention that the same
advice applies to newcomers here.
The reason is that you and erik simpson destroyed an agreement
we had between us back in mid-2015 to treat sci.bio.paleontology
like an embassy where we lay aside our personal grievances
[understood: the ones raging in talk.origins at the time]
and treat each other like the best of ambassadors.
The agreement lasted until early 2018, when erik refused
to apologize for a serious breach he had made in that
agreement right about when I went on a long posting break
in December 2017. Not only that, but he then gave a totally
different standard for his own behavior, and you backed him
all the way.
An accomplice of his who disappeared about a year and a half ago also backed him,
then helped him to continue in his dishonest, hypocritical ways.
When his accomplice crossed over a particularly sacrosanct line,
I boycotted their posts for the rest of 2019.
You, Harshman, raised a big stink about me doing that,
but I held firm, for several good reasons.
Perhaps, in the interest of restoring on-topic posting,
you should stop
making long posts about your personal grievances.

It seems ceratopsians were in demand in those days.
Incidentally, it's really unfortunate when scientists are unable to eat
their study organisms. My sympathy to paleontologists.

I know that, but you are behaving like a smart alec aged 8 years old or less.
Is your "sympathy" based on having eaten a good chunk of tinamou meat? Tinamous are the focal point
of your one claim to fame, a paper in PNAS co-authored with 18 (or is it 19?) biologists.

I have no such suspicions about Pandora. I think she was just humoring your first remark.

Are you really as deluded as that last sentence indicates?
In the first place, you are a known liar. I caught you earlier this year lying about me,

At the end of the latter post, I responded to some silliness by you as follows:
___________________________________________ repost ___________________________
And now there will be an endless series of back and forth attacks
resulting from this irrelevant seed.
What nonsense! You never replied to the post I linked at the beginning.
I expect the same to happen to this post.
================================= end of repost
Of course, my "expectation" came true, with not just the first post linked above
entering into the expectation, but with dozens of other such posts over the years,
where the evidence of your dishonesty was just too strong.
In the second place, you must have heard of the saying,
"De gustibus non est disputandum," ("there is no disputing about taste")
and yet, above, you have avoided giving any excuse for flouting this saying.
Third, your "everyone" is a lie. I doubt that you can name three talk.origins regulars
besides you and your perennial sidekick erik who publicly claim that I lack a sense of humor.
I can name at least one who saw a longish satire I did in talk.origins, and said publicly
that it showed that claims about me lacking a sense of humor are false.
I could go on, but I think it is more important to point out that I am NOT disputing the claim that I have no sense of humor. What I AM disputing
is your sincerity and integrity in saying "Shouldn't have to tell you."
You are guilty below of a dirty debating tactic which I call The One Shade of Gray Meltdown.
This consists of seizing on one or two things two disparate things have in common,
and pretending there is little or no difference between them.
So this is your way of avoiding becoming embroiled in interpersonal
conflicts?
I gave that advice to John Kerr-Mudd, a newcomer to both talk.origins
and sci.bio.paleontology. It is an excellent policy for anyone who
hasn't had many months of observation in talk.origins as to who is guilty >>> of dishonest behavior in interpersonal conflicts, and who is
honest and sincere, even in the midst of these conflicts.
I, on the other hand, have had a total of almost two decades
of interaction in talk.abortion, alt.abortion, talk.origins, and sci.bio.paleontology (often simultaneously) with people who
indulge regularly in dirty debating tactics, and so I am well
equipped to deal with them. John Kerr-Mudd may be well
equipped in other forums, but he needs to be able to have some
idea of where people are coming from before wading in.
I neglected to mention that the same
advice applies to newcomers here.

What hypocrisy! I've started two thoroughly
on-topic threads in just these past two weeks.
I don't think I have EVER seen you start an on-topic
thread in sci.bio.paleontology; certainly not in the last 7 years.
you should stop
making long posts about your personal grievances.
Dishonest misrepresentation. My main message above
was that the very existence of dishonesty and hypocrisy
in sci.bio.paleontology is the responsibility of yourself and erik,
and that third un-named former copious participant.
But then, I suppose you see nothing wrong with dishonesty
and hypocrisy when you and erik indulge in it.
