Quoting David Marjanovic <david.marjanovic@gmx.at>:
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...
