really wierd idea about Ichthyosaurs
ok, everyone agrees ichthyosaurs had humongous eyes.
We aren't sure if they had a mammal-like melon.
It's plausible an animal like this used sonar.
What if Ichthyosaurs used their eyes to recieve sound vibrations instead
of a melon? Perhaps not as true sound but as simple vibration info
-The eye is full of fluid (like a melon)
-The eye is huge in nearly all cases-larger than Mosasaurs, Plesiosaurs,
or Cetaceans. Perhaps larger than needed for sight alone.
-The eye is surrounded by very tiny bones that could transmit sound into
vibration (like ear bones do)
It's a strange idea but is it plausible?
