Helicoprion shown as chimeroid-like.
Finally an accurate depiction. A chimera, but with the build of the open-water apex predator it was.
Wonderful work! But why the absence of Pelvic fins? I see that a lot on depictions of Helicoprion.
Apparently, those few eugeneodontids known from whole fossils all lack pelvic and anal fins.
Hey...um...do you have any research papaers about this?
then..... HOW ON EARTH DID THEY MAKE BABIES?!
They could probably still guide each other.
Hmm, strange. I wonder what evolutionary purpose that would serve...
Not all structures necessarily have a purpose: such a state could have been due to extreme streamlining, or could have been due to an accumulation of mutations or deletions that causes the loss of those fins that did not negatively impact the ability of eugeneodontids' swimming ability.
Interesting. Makes sense.
While a new inheritable trait that confers an advantage enhances its potential to be inherited, an inheritable trait that does not impair its current owner's ability to successfully breed will also get a chance to be inherited, like, say, the situation of Huntington's Disease, a degenerative disease whose symptoms only begin appearing when the victim is in their 50's.
that puzzles me too
