Quoting David Marjanovic <email@example.com>:
Now, if we are considering the convolutions,
relative to cortex folding, then this is really nearly impossible
to tell in most fossil animals.
But it can probably be calculated quite safely. Today the folding is
neatly proportional to absolute brain size...
Surely not? Wouldn't a mammal and lizard brain of the same absolute
size have quite a different amount of cortical folding (favouring the
I imagine a large lizard (like a Komodo monitor) and a small rodent
could possibly have the same brain volume - I also imagine the
monitor's brain would be far less convoluted.
