Re: Supercroc

["Jaime A. Headden" <qilongia@yahoo.com>]

To the list, for a brief, not intended to be superiorly concise listing,
the various supercrocs....

  *Sarcosuchus tenerensis* and *S. imperator* are both from the Aptian to
Albian transition of Niger and Bahia, Brazil, and are crocodyliforms
related to the pholidosaur *Terminonaris.*

  *Deinosuchus rugosus/hatcheri* and *D. (Phobosuchus?) riograndensis* are
from the Campanian to Maastrichtian of central and eastern United States.

  *Purrusaurus,* a caiman (Alligatoroidea) is from the Miocene of Brazil,
and *Rhamphosuchus* (Crocodylidae, Tomisominae -- formerly a gavialoid
associated with *Thoracosaurus*) is from the Miocene-Pliocene of the
Siwalik Beds of India.

  *Leidyosuchus* and *Borealosuchus* are related, smaller crocs (not
really supercrocs, but bigger than any known saltie), alligatorids, from
the Paleocene-Eocene of the southern US to northern Canada.

  Hope this helps.

  Cheers,

  Little steps are often the hardest to take.  We are too used to making leaps 
in the face of adversity, that a simple skip is so hard to do.  We should all 
learn to walk soft, walk small, see the world around us rather than zoom by it.
