This Diplodocus centered storyline, was scientifically advised by the renowned expert on Sauropod Dinosaurs, K.Stevens of the Oregon University, USA. His greatest contribution, was spearheading what was then the growing trend amongst British and American Palaeontologists, that they should reposition the 'classic swan-necked' view of Sauropods, into an elongated horizontal form; with the Diplodocus unable to raise their necks above a certain low level not much higher than their own pelvis.
He also helped other episodes and the juvenile Diplodocus scene in this episode, with both puppeteer and Palaeontologist as well as Tim Haines the Director, actively furthering the science by doing practical experiments with the life like model head and neck. Kent Stevens himself remarked of how impressed he was by this.
Diplodocus Palaeobiology was yet again refined, thanks in no small part to the Walking With Dinosaurs Series. The Late Jurassic setting is tantilisingly over 68 Million Years after the previous Late Triassic episode - by far the largest jump in time in between episodes (The Early and Mid Jurassic was an equally exciting time, though the Mid Jurassic in particular is relatively mysterious and lacking of much fossil evidence globally, and also the series didn't need to visit these times because its continuity was brilliant anyway, following the general pattern of the changing Mesozoic world.
Even so, this time is fascinating and if a second series were to be made, one or two episodes could quite rightly fall into this large omitted time period)
This is the second episode of the series. This episode followed the life of a young female Diplodocus. After hatching at the forest edge, she and her siblings retreat to the safety of the denser trees.As they grow, they face many dangers, including predation by Ornitholestes and Allosaurus, and a Stegosaurus, which accidentally kills one while swinging its tail. Another one is killed soon after by an Allosaurus
Close to adulthood, the group of young Diplodocus are nearly all killed by a huge forest fire and fire storm that night, leaving three, then two survivors including the main female. They are driven out onto the open plains, where they find a herd.
The protagonist female mates, but not long afterwards is attacked by a bull Allosaurus. She is saved when the older female Diplodocus hits the predator with its whip-like tale. The Allosaurus leaves deep wounds on her side, but, as Kennet Branagh said, these will heal in time.
It is also noted that in time she shall become too great in size to be threatened by any existing land predator, reaching a grand old age exceeding 100 years (some Palaeontologists have theorized that they could have been much older somehow, like Giant Tortoises are, having lifespans exceeding 250-300 years. This would be interesting if proven correct)
- Anurognathus (Pterosaur)
- This episode contains the least non-dinosaur creatures of all the episodes.
- One of the hardest to create and longest to finalize animation shots in the series, took place in this episode. This is the panning shot in which we see Stegosaurus, unidentified Hypsilophodontids, (as yet) unidentified Anurognathus and then the main feature, a mighty herd of Diplodocus walking into the camera position as a column. The Sauropods took 75,000 times longer to create, than it took to view them on screen.
- The model for Othnielia was the same one used in Death of a Dynasty for Parksosaurus and would not be identified as Othnielia until it was reused during The Ballad of Big Al.
- The appearance of Anurognathus in this episode is incorrect as they actually lived in Europe.
- Sadly, despite being his greatest contribution to the field of Palaeontology, Kent Stevens theory about the neck posture of sauropod dinosaurs is know known to be completely incorrect following studies conducted by Michael Taylor and Mathew Wedel.
- The original program was formatted for a less mature audience as "Prehistoric Planet" for Discovery Kids.
