Fold at the corner of page describing animal organ (6)

I believe the answer is:

dogear

I'm a little stuck... Click here to teach me more about this clue!

'fold at the corner of page' is the definition.
I know nothing about this answer so I can't judge whether this works.

'animal organ' is the wordplay.
'animal' becomes 'dog' (type of animal).
'organ' becomes 'ear' (the ear is an organ).
'dog'+'ear'='DOGEAR'

'describing' acts as a link.

Can you help me to learn more?

(Another definition for dogear that I've seen is " sort of page-turner".)

I've seen this clue in The Irish Times.
