nasal arch वाक्य

"B . salgadoi " is further evidence that, after a purported extinction of diplodocid sauropods, some lines of titanosaurian evolution converged with them, exhibiting low long skulls without the characteristic nasal arches of other macronarians ( such as " Brachiosaurus " or " Argentinosaurus " ) and lower jaws that were squared off and contained comb-like teeth, reversed limb proportions ( the front limbs shorter than the hind limbs, unlike the condition in most other macronarians ) and rudimentary whiplash tails.
