* Dino to bird problem

Here is something noteworthy concerning the dino (non-maniraptor coelurosaur) to bird idea:
There are fossils for a number of taxa in the fossil record. But none of those work out as ancestors. 
Thus it strains credulity that the dino to bird enthusiasts fall back on the story that there is a lack of fossils. 

THERE IS A COMPLETE LACK OF FOSSILS ON THE PURPORTED DINO* TO BIRD LINEAGE.
That is the dino to bird problem.

But as folks must know by now, my main interest is in presenting the case for  pterosaurs as the ancestors of birds, not hashing and re-hashing the problems with the dino to bird idea. .


*Note again that by "dino" I mean non-maniraptor coelurosaurs. They are not ancestral to birds.
