Re: Turtles and Crocodylians are not Reptiles - no? What are they?
Turtles are the closest to archosaurs now?
That's a hypothesis with a pretty venerable history. It came from doing
cladistics with five characters and no fossils. Outside of two or three
German universities it's extinct. Except, that is, if we take the molecular
version -- almost all molecular analyses put the turtles either as the
sister-group of Archosauria or as the sister-group of just the crocodiles
Now you are grouping them firmly within Diapsids at a specific position?
closer than lepidosaurs (snakes and lizards?) and squamates(tuataras)?
You mean squamates (lizards including snakes) and lepidosaurs (squamates and
There are morphological analyses (Rieppel, deBraga, Reisz and others in
various combinations) that put the turtles within Lepidosauromorpha, as the
sister-group of either Euryapsida or Lepidosauria. Part of my thesis work is
to find out if they are wrong.
