Dance of triplets in later natal development (10)
I believe the answer is:
tarantella
'dance of triplets' is the definition.
'tarantella' can be an answer for 'dance' (tarantella is a kind of dance). I am unsure of the 'of triplets' bit.
'later natal development' is the wordplay.
'development' is an anagram indicator.
'later'+'natal'='laternatal'
'laternatal' is an anagram of 'TARANTELLA'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for tarantella that I've seen before include "merry dance" , "furious dance" , "Whirling dance" , "Lively Neapolitan dance" , "dance music" .)
