Pterobranchs!!!

["Matthew Bonnan" <mbonnan@hotmail.com>]

Quick question (or am I going crazy?):

I am preparing my lecture on "simple" animals and lophotrochozoans tomorrow 
and noticed our textbook places the pterobranchs right in the middle of the 
protostomes!!!  Have I missed something?  Has there been a change in how we 
view pterobranchs -- was there a new study that showed they were really not 
deuterostomes?

Just thought somebody out there might help me here -- I swore they were 
hemichordates!  Please answer me off-list ... and I apologize for this not 
being a dino-related post ... although it is chordata ... sort of. =)

Thanks in advance,
