Re: Precocial young Re: Yabeinosaurus, earliest viviparous squamate



 How much parental care is there with these live birth reptiles?

In squamates? None that I can think of.

 Does this mean parental care evolved with live birth, or would the
 young have been first been precocial, and parental care evolving
 later?

These two characters are independent. You can have live birth without parental care (as in at least some extant live-bearing squamates), and you can have parental care without live birth (as in extant crocodiles and birds).
