-- Scientists have confirmed the oldest penis-like structure in an ancient fish specimen.
The discovery of the 400 million-year-old reproductive organ is one of the earliest examples of internal fertilization in vertebrate animals. Understanding the anatomy of these ancient fish could reveal further details in the evolution of vertebrates -- including humans.
The research is published in today's advanced online ahead of print edition of Nature.
Earlier this year the team, led by Australian palaeontologist Dr John Long, predicted some ancient fish from the Devonian era, had an attachment to their pelvic bone, which were used by males to fertilize females.
Long, of Museum Victoria, said "when we announced we'd found some structures in the pelvic fin that suggested copulation, we hadn't found the business end of how they were doing it."
Now the team have identified a long clasper, made entirely of bone, on another fish specimen. Long said claspers were used by the ancient fish, an extinct class of armored fish called placoderms, to grip inside the female while they were mating.
"It's a pretty big find because placaderms were the dominant fish for 70 million years, but we knew nothing about their reproduction," said Long.
He said their work earlier this year suggests the reproductive structure in the dominant group of placoderms, called arthrodires, was similar to present-day sharks.
"Now we've actually found it, a specimen with an undoubted clasper with a knobbly end."
STAYING power. For real.
"So that's where I left it!"
That last line is a puzzler....
Yeah...I don’t think they know whether he was coming or going...
"(sigh) It's always nice to remember your first again..."
Whoa! This day is getting to be too much for me.
So should I go fishing for a well hung dugong?
How did they convince Larry King to let them test his %@#&?

Thinking the same thing. Looked down the other day and didn’t see anything.
Now I know where I left it, 400 million years ago. Guess I am older than dirt.
"Now we've actually found it, a specimen with an undoubted clasper with a knobbly end."
Imagine it said with a British accent.
Ewwwww. And he was probably wearing a "Members Only" jacket. Ewwwww.
400 million year old male sex member found.
Is this about Hugh Hefner?
LOL
Old fool goes around in his pajamas to be ‘ready for action’.
Thinks he’s still sexy- too dumb to know those women only want his money.
LOLOL, tet.
If you have an erection which lasts for more than 4 hours...
A 400 million year boner!??
I think it’s the Viagra drip or the Cialis suppositories either one.
an undoubted clasper with a knobbly end
Oooooh, you mean a FRENCH clasper!
I got one of those at a truck stop in Portland once.
I think they called it a “Hunt Bros. Mud grip”
or something like that.
Anyway it said it was “All for HER pleasure”.
