The fact that mammals and reptiles wrap their embryos within these defenses makes them known as amniotes, which first evolved about 310 million years ago. The fossil record of amniotic eggs and embryos is paltry, leaving scientists little knowledge about when, how and why they evolved.<quoted text>
I think some of the New Testament was written by the apostles. I think some was abridged to include the oral stories too. No I don't think any stenographers were there for sure.
The reproductive organs wouldn't have to be the only clue. We know that Dinosaurs laid eggs and saber tooth tigers had live births.
I would just think if at some point crocodiles began having live babies over the course of whatever period of time, there would be some evidence of that major change. Especially if people are going to base their beliefs and theories around such a claim.
Scientists have typically assumed that egg-laying emerged before live birth in amniotes, since earlier creatures such as amphibians and fish are typically egg-layers. However, the earliest direct evidence of reproduction in amniotes to date is dominated by specimens that gave birth to live young
