They were also at times barely surviving. They might not have had much interest in sex. Even if they did, the mother's reproductive processes may have been reduced due to lack energy/nutrition. You also don't know how many stillbirths they had. It's probably not something they would readily talk about, (and not something that the geologists were eager to discuss).
