Hey guys it's Kerry happy dinosaur day I'm looking at my sauropods
Diplodocus the long neck may have been used to
forage for food in forests that would have been inaccessible due to their
massive size and also for poking their head into wetlands to get mosses and
ferns where they could stand on firm ground
Sauropod lifespans may have been of the order of a hundred years

another Diplodocus Diplodocus had a row of spines running down its back its
backbone had extra bones giving its name which means double beam these would help
support and move its neck and tail it may have used its whip like tail for
protection diplodocus could not hold their
necks over about five meters off the ground
at the end of this video I'm going to draw and paint this Diplodocus
diplodocus roamed Western North America during the late Jurassic period I would
love to read any of your amazing sauropod facts
ampelosaurus was a medium-sized sauropod from
the late Cretaceous Period it had a long neck and walked around on four thick but
slow legs it was a type of titanosaur it was closely related to saltasaurus
it had armor-like plating called osteoderms that ran all the way down its
back to the beginning of the tail it may have been for extra protection against
the powerful jaws of predators
Alamosaurus lived during the late Cretaceous Period it was a gigantic quadrupedal herbivore
with a long neck and tail and relatively long limbs
its body was at least partly covered in bony armor alamosaurus appears and
achieves dominance in its environment very abruptly which might support the
idea that it originated following an immigration event from South America
Apatosaurus lived during the late Jurassic Period and was one of the largest land
animals that ever existed its small head had a long skull and was less than two
feet or 60 centimeters long with its nostrils on the top of its head
it had a long 15 meter whip like tail and four massive slow moving column-like
legs it's hind legs were larger than the front legs fossilized footprint tracks
have been found that were about three feet or one meter wide
the lufenggosaurus was a herbivore from the early Jurassic period this strange
dinosaur had large powerful hind legs and smaller arm-like front legs it could
use its strong back legs to stand straight up to reach the top of trees it
then used its arm like front legs to put the food into its mouth
it had sharp claws but an especially large thumb claw which could have been
used for breaking foliage from the trees
Europasaurus lived in the late Jurassic period it was unusually small
for a Jurassic sauropod it was a dwarf dinosaur that lived in present day
Germany this dwarf species developed due to the limited amount of available food
on the island that it lived on its head was very small with a crest on top it
had short and stocky legs with a thick and moderately long tail the
europosaurus was a herbivore like other sauropods it derived its sustenance from
the shrubs and trees of the European Islands
Plateosaurus or flat lizard lived in the late Triassic through to the
early Jurassic period it had a long tail long hind limbs and a small head at the
end of a long neck the teeth were leaf shaped and the jaws beak like although it
walked on four legs paleontologists believe it could rear up on its hind
legs and use its powerful clawed hands to pull in succulent branches
P lateosaurus belonged to a group known as the prosauropods and was a relative
although not an ancestor of the gigantic sauropods of the Jurassic and Cretaceous
Period Rhoetosaurus lived in Queensland
Australia it is a genus of sauropod dinosaur from the Jurassic period of
what is now eastern Australia it had powerful elephant-like legs and its
name means Trojan reptile it had an average build of up to 17
meters or 55 feet in length and weighed around 20 tons
Argentinosaurus dinosaurs I've got twins it may have been the largest dinosaur it
had a long neck a long tail and a small head it probably used its long neck to
reach into conifers or sweep the ground in search of ferns and bushes
Argentinosaurus laid eggs about the size of a rugby ball
Brachiosaurus I really like the green color on this dinosaur
it lived during the middle to late Jurassic period it was one of the
tallest and largest dinosaurs it had a long neck small head with the nostrils
on the top of the head and a short thick tail
Brachiosaurus lived on land most Predators like Allosaurus and
ceratosaurus were half its size their best defense was their size plus their
clawed feet and tail
Camarasaurus lived in the lake Jurassic period it had a small square-shaped head with a blunt
snout it had a long neck thick legs and a long tail which served as a
counterbalance to the neck its front legs were slightly shorter than the hind
legs camarosaurus had five toes on the front
feet with a long sharp claw on the inner toe which was used as a weapon against
predators natural enemies of young camarosaurus
would have been Allosaurus ceratosaurus and torvosaurus
Jobaria lived during the Cretaceous Period
it used its scoop-like teeth to eat plants and had a long flexible neck it
had one large claw on the inner toe of each front foot and smaller claws on its
hind feet its neck contained 12 vertebrae
Jobaria fossils have been found together which indicates that it was a
herding animal
a juvenile Brachiosaurus dinosaurs reproduce by laying eggs
the babies that hatched out of Sauropod eggs were generally no bigger than a
modern adult goose Diplodocus a really nice model and I
love the tail there it's front legs were shorter than its
back legs it had elephant-like legs with five-toed feet notice that large thumb
claw its head was less than two feet with nostrils on the top of the head it
was among the longest land animals ever it may used its whip-like tail and claws
for protection
Cetiosaurus lived during the late Jurassic period it was a huge long-necked
long-tailed dinosaur with a tiny head and a bulky body although it had a
shorter tail and neck than most Sauro pods the four limbs relatively long and
it walked on all four legs
this dinosaur was originally thought to be a crocodile-like animal its name
means whale lizard
this is a Brachiosaurus hatchling you can see it's just coming out of the eggs
there this is all part of a life cycle series
and here's the juvenile the clawed feet in the young we're extra
long
and the adult size size it grew to about 85 feet or 27 meters
and weighed up to 88 tons Brachiosaurus had about 52 teeth 26
teeth in each jaw it's used its chisel-like teeth to graze
the tops of the trees swallowing food whole
Apatosaurus may have used its tail as a third leg in order to reach and graze
very tall vegetation Apatosaurus hatched from enormous eggs
that were about one foot or 30 centimeters in diameter
the vertebrae had a groove along the top this held a strong ligament that
supported the weight of the neck and tail like the cables on a suspension
bridge the tail would counterbalance the head I really like this model and I've
painted a picture of this actual model I'm going to show it to you at the end
Brachiosaurus I really like the green color of this model it's really nice
lots of good detail there too brachiosaurus walked on four legs
notice that the front legs were longer than its hind legs the longer front
legs and it's very long neck made Brachiosaurus look rather giraffes like
reaching heights of up to 40 to 50 feet tall
some of these long-necked creatures would have been engaged in neck slapping battles with rival suitors for the chance to make with a female as giraffes do
today Daxititan it was a very large dinosaur
reaching up to 69 feet or 21 meters in length it had an enormously long neck
which helped it find leaves and plants I really like all the detail on this one
and the color and lots of osteoderms
with reproduction for copulation to occur an amorous male would have to
position his cloaca (which is the orifice used for both expelling waste
and mating) right up to the cloaca of the female
a male sauropod would probably have to rear up at a relatively oblique angle or
slanted stance and the female would have to assist by moving her tail to the side
Brachiosaurus each foot had five toes with a long
sharp claw on the first toe of each foot and the claws on the first three toes of
each rear foot
this sculpt is excellent and the head turns back like the dinosaur is looking
to see if there's any danger around very good detail on the head there
when the two cloaca are pressed together sperm passes from the cloaca of the
male into the cloaca of the female which leads to fertilization
have a look at that that's really nice notice on the front feet the toes are
long and column-like in a vertical position giving extra height and that
giraffe-like appearance
and here's another quick look at Apatosaurus and my painting I did of it
I drew it freehand and then just painted and texted it in
cool dinosaur
even though a male sauropod would have rested a great deal of weight on the
back of the female during mating the stresses and strains would not have been
any more severe than those caused while the female dinosaur was walking
when you think about it walking requires shifts in weight as the dinosaur
balances and goes through each step cycle and so with dinosaur skeleton
would have been strong enough to cope with this
and here's my artwork
