Walking with Dinosaurs: Silesaurus

Silesaurus opolensis
Named by Jersy Dzik, 2003
Diet: Herbivore
Type: Dinosauroform (Silesaurid) dinosauromorph ornithodirian archosaur
Size: 7.5 feet (2.3 meters) long
Region: Europe (Poland)
Age: Late Triassic (230 to 228 million BC; Carnian stage)
Episode:  Sea Monsters- Dangerous Seas (6th Most Dangerous Seas) (as "Coelurosaur")
Info: Living in what is now Poland some 230 million years ago in the Carnian stage of the Late Triassic period, this herbivorous reptile was not a dinosaur at all as it lacks the dinosaurian features that includes an enlarged deltopectoral crest (a muscle attachment on the humerus), and epipophyses (enlarged tendon attachment above the postzygapophysis) on the cervical vertebrae and it is instead a dinosauriform, a clade of archosaurian reptiles that includes dinosaurs and their most immediate relatives. However, Silesaurus does have characteristics it shares with dinosaurs such as a brevis shelf (a bone surface on the ilium that functions as an attachment site for tail muscles), an ischium with a slender shaft, a femur with a reduced tuberosity that borders the ligament of the femoral head, a prominent lesser trochanter, an overlap of the ascending process of the astragalus with the tibia, and a concave proximal articular surface for the reception of the distal end of the fibula on the calcaneum.

So years ago, I was wondering what creature should I replace the unnamed coelophysid that mispronounced as "coelurosaur" that appear in Sea Monsters, because:
 

• First off, the model of the coelurosaur is actually an already used model of Coelophysis.
  
• Second, while fossil remains of members of the coelurosauria were mainly found from the mid Jurassic to the Cretaceous, possible remains of coelurosaurs may have been found as early as the Late Triassic, but this is speculative, because of the fragmentary nature.
• Third, the segment is set mainly in the Carnian stage of the Late Triassic period, where some of the earliest-known remains of dinosaurs were found in rocks that date back at that time, which is pretty old for coelurosaurs.
