Creationist comment:
So little is given in holotype, sorry, in specimen C, I am not sure it can be excluded it was a real "titan" or "human shaped but gigantic mighty one" of the nephelim.

But I am not an anatomist or palaeontologist. I am not one of the medicine students of my family.

The other two specimens have bones identified as caudals, i e tail bones.

Guaibasaurus candelariensis

Guaibasaurus candelariensis was a dinosaur that lived during the Late Triassic (Norian) Period. A saurischian of some sort, apparently more primitive than Herrerasaurus and Staurikosaurus. Remains of Guaibasaurus were discovered in Rio Grande do Sul, Brazil. Two partially complete specimens have been attributed to Guaibasaurus, the first was described in 1999 both specimens lacked the discovery of a skull. Guaibasaurus had three full fingers and two vestigial ones on each hand, like Herrerasaurus. This animal may have grown to lengths of around 6.6 feet (2 metres). The reconstruction of the head is hypothetical as no skull has been found.

Tupuxuara

Tupuxuara is a crested and toothless genus of pterosaur from the Early Cretaceous of Brazil. Three species have been recognized, all from the same Santana Formation: T. longicristatus, T. leonardii and T. deliradamus. Females and males have slightly different crest indicating sexual dimorphism and is a mark of adulthood as juveniles are crestless (Martill & Naish, 2006). Tupuxuara, judging by the wing wing proportions and the general environment where it lived, as well as the lack of any adaptations to piscivory, was most likely a terrestrial generalist, much like other azhdarchids and modern secretary birds and seriemas.

Thalassodromeus sethi

Thalassodromeus is a pterosaur from the Early Cretaceous of Brazil. It had an extraordinary large skull surmounted by a huge bony crest. The crest was irrigated by blood vessels and might have been used for body temperature regulation. The beak is similar in shape with the one of the modern skimmer (Rhynchops) and it was suggested that Thalassodromeus might have had a similar feeding strategy. However, new biomechanical studies of the neck show that its unlikely that it was a skimmer. The scizzor like jaws indicate it might had been a scavenger, or an aerial piscivore that used the jaws to grasp prey rather than skim.

Ornithocheirus

The name Ornithocheirus ("Bird hand") was coined by paleontologist Harry G. Seeley in 1869 to describe a number of pterosaurs fragmentary bones found in the Early Cretaceous Cambridge Greensand, England. He placed the different pieces up to 28 species of Ornithocheirus. Since then, the genus has become a terrible wastebasket taxon with over 40 species described from fragmentary fossils from the Early Cretaceous of Europe (England, France, Czech Republic) and South America (Brazil).

To add to the confusion, several species were transfered to a number of different genera including Criorhynchus, Coloborhynchus, Lonchodectes, Anhanghera and Tropeognathus. At the end, it is possible that none of the numerous species of Ornithocheirus is valid. A generic portrait of Ornithocheirus described it as a medium to large size pterosaur with a wingspan of 4 to meters. characterized by a long narrow and toothed jaws with a crest on top of the anterior portion of the snout.

Sacisaurus agudoensis

Based on a few fragmentary remains, Sacisaurus was apparently a smaller relative of the polish Silesaurus. This little beaked herbivore was a precursor of the ornithischian dinosaur.

Ludodactylus sibbicki

The specific name of this large pterosaur honors famous paleoartist John Sibbick. Ludodactylus was a crested ornithocheirid from the Early Cretaceous of Brazil, known from a single nearly complete skull missing the distal end of the crest. It was preserved with a leaf between its mandibles thus its nickname, the "tree-biter" and on the same slab that contain the fossils of the fish Dastilbe. The generic name refered to the fact that the animal resembles the inacurrate popular depiction of toy Pteranodon with teeth (Pteranodon was crested but toothless). It may turn out that Ludactylus is the same animal than Brasileodactylus.
