That work bolstered the idea that placoderms werent, in fact, their own odd group that dead-ended hundreds of millions of years ago some were actually the ancestors of bony fish (and thus humans). But it was just one fossil, Ahlberg notes. You dont want to draw too big of conclusions from one animal.
Two animals, though, is a different story. Qilinyu, the new fossil Ahlberg and colleagues describe, had an armored skull and trunk and was probably about the length of a box of tissues. Like Entelognathus, Qilinyu has a three-part, bony fishlike jaw, though the creature looks a bit more like a typical placoderm, Ahlberg says. The two fossils form almost perfect intermediates between placoderms and bony fishes, he says. Ahlberg and his colleagues suspect the key jaw elements of bony fish (and all land vertebrates) evolved from those bony blades of placoderms.
That jaw arrangement just happened to be the most successful one in the environment over evolutionary time, and those who had it seemed to out survive their com padres.
No junior, you are not related to a fish. But maybe you should be.
The laws of evolution are evidently as politically correct as global warming science. This is evidenced by evolution laws being revised every time a dog digs up a strange bone in the backyard.
if you notice the shark’s tooth first, I have some news for you...
That’s a Meglaboobdon tooth.
Re: “But it was just one fossil, Ahlberg notes. You dont want to draw too big of conclusions from one animal.
Yeah, when have Darwinists ever done that?
It was a long way to the Coelocanth. (Which still exists).
I'd say it was from a Megalodon.
She is not ETL’s sister?
I recognize it....the shark tooth is cool too.
Paleontologists may study and comment on one fossil but wait until that fossil’s information is confirmed by another or, hopefully several. In human fossils, for instance, Lucy was confirmed by other finds and by having some 40% of her skeleton. She was the first but Donald Johnson compared her with other similar creatures found over a wide area and from a long time period. Arid was older but much the same as were finds at numerous locations.
The study of Lucy is a good example of vigorous debate and controversy before a find is finally defined and new discoveries may change conclusions even then.
Megladon is the tooth, unfortunately I do not know the rack. Does your sister date old married men?
I don’t care how armored the fish is, we shouldn’t be letting anyone or anything rewrite our history.

Lol! I don’t even have a sister. :)
A sharktooth bit your sister.
It’s late; I’m tired. I thought this was about the history of the Jews.
I guess you could call it a distant prehistory.
