@gungasnake,
for someone who is basically clueless what this information means, I can only assume that this "body blow"story has been fed to you with a Creationist Spoon?
This is a 10 yer old find. The authors reported much more than the details of jaw attachments.
This fish actually showed the first evidence of viviparity, the damn thing had a fetus attachd by an umbilical(jut like shrks) . this pushes back viviparity by 200 million years
The jaw musculature of a placoderm is a mighty interesting thing, its armored, the only thing this critter does is to allow us to see how jaws tth and rticulte. Early stories about plcoderms were made from poor quality fossils from Pennsylvania, Quebec and England, a species known s
cnthodes. This Australin specimen appears to be an example of a later species type , called the
Arthrodires.They were found in a geologic unit called a
Lagerstatte which is a sedimentary unit of really fine grained sediments which have preserved the fine detail of the fishies body. Its like the Burgess SHale.
One question, How do the Cretinist Ministries explain the age of the specimens.? It is early Devonian is it not?
Im so glad that your "ministry" can quickly assess the fossill only 8 yers after its early report in NATURE. Science tries to nlysze, Cretinists merely "preach".
