Questions about birds
I have to write a report about Archaeopteryx and the origin of birds,
that's why I have so many questions. Don't be afraid!
I would like to get some information about Gobipteryx.
Is this animal a dinosaur or a bird? When was it found?
What are the features which link it to the modern birds
and to the dinosaurs? Is he toothless? In what geological
period did he live? Which part of his skeleton was discovered?
I also would like to know if Concornis, Sinornis, and Iberomesornis
belong to the Enantiornithes or to another group of aviens.
I don't really know if some work about their phylogeny exists,
so I imagine a phylogeny like that:
/____ Archaeopteryx____birds like Concornis_____/__Ornithurae
Is this possible? Can anybody tell me if there are mistakes?
Please, help me!!!!!!!!!!!!!!!! (desperate voice)
Many thanks, in advance,
