The bird seen at 1:12 on the DVD is
probably Archaeopteryx judging by the large
frond-tail.
At the beginning of the episode, it looks as if the Butlers
and cave-dwellers are harvesting pomegranates, supported by
Tana's comment that Kim has said they are high in
vitamin C (though it seems unlikely Tana would know the term
"vitamin C"!).
The small bipedal dinosaurs seen at 2:27 on the DVD may be
Compsognathus. Also seen are a Dimetrodon,
a protoceratopsid, and a carnosaur that appears to be the
same species as the "Tyrannosaurus" called Konga by
Gorok in "What
Goes Up"
(Gorok refers to the species as "zondi" in this episode).
Using a fruit as a ball, Greg tells Tana he's going to throw
Glump a Sandy Kofax curve. Kofax was a pitcher for the
Brooklyn/Los Angeles Dodgers major league baseball team from
1955-1966.
Gorok refers to the leader of the pack of zondi as Skarak.
The pack is from the Valley of the Smoking Water, which is
shown to be a bed of steam geysers.
The pterosaurs seen at 5:52 on the DVD appear to have some
rudimentary feathers on parts of their bodies. It's body
doesn't quite match to any pterosaur species I can identify.

Some wolf-like predators are seen at 6:47 on the DVD. These
may be the prehistoric dire wolf, which existed on the South
American continent during the Pleistocene epoch, whereas the
modern wolf is not found there.
At 8:06 on the DVD, a couple of the zondi are seen snacking
on some leaves, despite being carnivores. It may be that
they eat these types of leaves for their medicinal
properties, like a dog eating grass.
After climbing down into the cave with Tana, Greg says it
makes him feel like Tom Sawyer with Becky Thatcher, lost in
Injun Joe's cave. This is a reference to Mark Twain's 1876
novel The Adventures of Tom Sawyer, part of which
involves Tom and his girlfriend, Becky Thatcher, getting
lost in a cave used by the criminal Injun Joe as a hideout.
Besides the similarity to the novel, it's possible Greg's
line here indicates an unspoken affection for Tana beyond
just friendship.
At 11:44 on the DVD, Kim and Gara share a nice bonding
moment when they both recognize a common trait among the men
of their respective civilizations.
Gorok describes the
Dimetrodon
as a fish eater, which is largely believed to be true of the
species, but also eating small reptiles, amphibians, and
mammals.
The birds seen at 12:06 and 12:53 on the DVD appear to be modern
birds, rather than Archaeopteryx or another
prehistoric forebear of birds.
At 12:36 on the DVD, Kim is astonished by a dog-sized mouse
living in the jungle. I am not aware of any mouse species
capable of reaching that size, even of the prehistoric
variety (though a few species of prehistoric rat are close
to small dog size).
The large birds seen at 13:14 on the DVD appear to be
vultures, perhaps the Andean condor, though it would be a
bit out of its accepted range of habitat in the Amazon.
Greg remarks that the
Valley of the Smoking Water looks like Yellowstone Park.
Yellowstone National Park in Wyoming has a number of
geothermal geyser basins.
For some reason, Glump is depicted with fangs in his mouth
at 16:37 on the DVD!

It seems unlikely that the Butlers' makeshift steam hose
would work without something to stop up the geyser around
the hose at the base.
John suggests that his family might be able to build a
geothermal electrical generator in the
Valley of the Smoking Water
to contact the outside world (Gorok remarks that the zondi
probably would not like it). In the later episode
"S.O.S.",
the Butlers do build a wind-powered generator in order to
use their damaged radio equipment from the raft to contact a
jet plane that has begun to fly a daily route over the
Valley of the Dinosaurs.
