Conclusions about the Fossil Record 

The record of terrestrialization is a somewhat confusing one.  It is one the most studied record s of its type and is an endless source of debate.  There exists many provokative finds indicating a lineage trail, but their also exist noticable gaps in the record that spurn researchers on.

The fight is further complicated by the host rocks that contain the fossils that will shed light on the debate and maybe answer questions about lineage in a concrete way as is seen with the scorpions and vascular plants.

For now, the record is complete in the sense possible directions for lineage, but incomplete in diffinitive answers, like much of paleontology.
