Skull depth vs PCRW.

A graph demonstrating the spread of data between morphotype one (open circles), morphotype two (filled circles) and Pterodactylus antiquus (open square) in respect to their skull depth and the length of their PCRW. Solid black lines = regression lines for respective morphotypes; dashed grey lines = 95% confidence limits.
