I would also like to reinforce what Tom H., John H., and others have
said regarding the use of web-based references.
A couple of years ago, I got a call from a woman about her daughter's
homework assignment. Her daughter (2nd grade, if I recall correctly)
was in a class in which the teacher assigned each student a different
extinct animal and then asked for presentations of a given length (I
no longer remember how long). Her daughter's assigned animal was
(Interestingly, she did not call for me specifically - she simply
called the Field Museum and asked for a paleontologist. No one at
the Museum's switchboard knew I had ever looked at any crocodyliform,
much less Deinosuchus. This was simply a stroke of luck for her.)
Anyway, she was having difficulty finding published information on
Deinosuchus. I was not surprised (and said so), as there is very
little we can actually say about Deinosuchus - it was big, it is
typically found in estuarine or coastal deposits, it's known only
from the Campanian (maybe lower Maastrichtian) of North America, and
so on. I honestly didn't think it was an appropriate choice for a
second-grader, and eventually advised her to ask her daughter's
teacher for a different animal for her daughter.
What horrified me was the "information" she had pulled off the web
for her daughter.
Her: "I mean, we DO know, from the web, that Deinosuchus' jaws were
unfused in the middle so they could stretch their mouths like
Her: "You mean they can't?"
Me: "Absolutely not. Most croc jaws are unfused at the middle [the
symphysis]. but there isn't any mediolateral movement there."
Her: "Oh." (short pause) "But it IS true, isn't it, that they
only ate dinosaurs?"
Me: "We've never found gut contents (at least none that I would
accept), so for all we know, they independently evolved chloroplasts
and so on.
Moral of the story - the web can be a valuable tool, but unless you
know who is providing the information, it shouldn't be used instead
of a well-stocked library.
