Those are officially known as "Scientific Wild-*ssed Guesses" -- SWAGS, for short.
Swags are essential to the scientific process -- they come before confirmed theories, before scientifically stated hypotheses, they've been called "brain storming", wherein a scientist considers all potential explanations.

Work on fossils like Sahelanthropus tchadensis typically includes a mixture of observed facts, confirmed theories, falsifiable hypotheses and, yes, some imaginative Swags.
Scientific writings are supposed to clearly distinguish which of those it's referring to.
