Read on.
After Table 2 you'll proceed to Figure 2 sometime.
It contains all 4 examined fatty parts.

Well Figure 2 doesn't multiply the compositions of the examined parts
with the weigth to be expected for each.
Furtunately we have a table that shows how big various parts of an
animal are for example. (

I see the skin had 572g fat, compared to 440g in the muscles.
you're right, the skin has more fat than muscles. But not much.
And in farmed beasts you have adipose cells inside of muscles.

Marine mammals you can skip or humans wouldn't have developed inlands
(like rift valley, east africa). I wouldn't believe either that dougongs
were enough to fill the gap after male emus have left the egg, or were
all killed. Thanks god there are some dougongs left.
What were the next fat items in the summer?
Cordain's elks were butchered at fall, a fatty season where the winter
is cold, btw..
>farm animals used to be fattened up on corn. high carbs.
Farm animals are fattened with the *cheapest* calories. Mostly this is
corn, right. But feeding fat fattens even better. And it's done with any
fatty waste. Expeller pulps (e.g. from sunflower). Ground meat waste. ..

I think I saw the citation a few days ago at BenBests or one of the
Cordaine articles.
With 22 g DHA/EPA I'd surely fear for my brain and AA depletion.
AA smells dangerous when used to make bad eicosanoids.
But the brain seems to need it. And it is displaced by DHA.
If EPA intake is so high I'd fear imune suppression (read at Ben Best
about it).
I don't think it's advisable to play around with such non-paleo
supplements like fish oil too much.
The 1-2 daily grams Ben Best recommends are already based on therapeutic
considerations. They would be hard to eat even when eating all reachable
brains (the only inland source of DHA).
Brain has 0.5 g DHA per 100g (
http://www.juggernaut.com.au/food/?f=brain&n=13318 )
And a kangaroo brain is only 68 grams "heavy".
