Compsagnathus

Compsognathus are a species of chicken sized dinosaurs that first lived on earth 66 million years ago and reappeared in the mezosoic island. they are very tactical for their size and manage to take down even humans with their venomous bite not seen in actual compsognathus but this trait seems to be from Michael Chrichton's Jurassic Park. The Compies as they are called are usually seen traveling in groups of 10-20 and they can connect with each other with telepathy to allow each other to alert what is in the area. As a Tag Team class creature(Subclass:Attacker), Compsoganthus are the size of domestic chickens. during wars they wait for soldiers to get pushed down before rushing and biting them on their bodies to enject their venomous saliva.

## Biology

For decades, *Compsognathus* was known as the smallest known non-avian dinosaur, although some dinosaurs discovered later, such as *Mahakala* and *Microraptor*, were even smaller. The German specimen was estimated to be 70–75 cm (28–30 in) and 89 cm (35 in) in length by separate authors, while the larger French specimen was estimated at 1.25 m (4 ft 1 in) and 1.4 m (4 ft 7 in) in length. The height at the hip has been estimated at 21 cm (8.3 in) for the German specimen and at 29 cm (11 in) for the French specimen. The German specimen was estimated to have weighed 0.32 kg (0.71 lb) and 0.58 kg (1.3 lb), and the French specimen 2.5 kg (5.5 lb) and 3.5 kg (7.7 lb). Compared to other compsognathids, the larger French specimen would have been similar in size to larger *Sinosauropteryx* specimens, but smaller than *Huaxiagnathus* and *Mirischia*.

*Compsognathus* were small, bipedal animals with long hind legs and longer tails, which they used for balance during locomotion. The forelimbs were smaller than the hindlimbs. The hand bore two large, clawed digits and a third, smaller digit that may have been non-functional. Their delicate skulls were narrow and long, with tapered snouts. The skull had five pairs of fenestrae (skull openings), the largest of which was for the orbit (eye socket), with the eyes being larger in proportion to the rest of the skull. The lower jaw was slender and had no mandibular fenestra, a hole in the side of the lower jawbone commonly seen in archosaurs.

The teeth were small and pointed, suited for its diet of small vertebrates and possibly other small animals, such as insects. The German specimen had three teeth in each premaxilla (front bone of the lower jaw), 15 or 16 teeth in each maxilla, and 18 teeth in the lower jaw. The French specimen had more teeth, including four in each premaxilla, 17 or 18 in the maxilla, and at least 21 teeth in the dentary. Compsognathids were unique among theropods in having tooth crowns that curved backwards at two thirds of their height, while their mid-parts were straight; also, the crowns had expanded bases. In *Compsognathus*, the frontmost teeth of the upper and lower jaws were unserrated, while those further back had fine serrations on their rear edges. In the German specimen, the crowns were around two times higher than wide in the front of the jaws but diminished in height further back, with the last tooth about as high as wide. The German specimen also shows a diastema (tooth gap) behind the first three teeth of the premaxilla. As such a gap was not present in the French specimen, Peyer suggested that additional teeth were possibly present in this region the German specimen.

The number of digits on the hand of *Compsognathus* has been a source of debate. For much of its history, *Compsognathus* was typically depicted with three digits, as is typical for theropods. However, the type specimen only preserved phalanges from the first two digits, leading to the suggestion that *Compsognathus* bore only two functional digits, with the third metacarpal being extremely slender and reduced. Study of the French specimen indicated that the third digit bore at least one or two small phalanges. However, there remains no evidence for an ungual phalanx on the third digit, so the digit may have been reduced and non-functional.

Some relatives of *Compsognathus*, namely *Sinosauropteryx* and *Sinocalliopteryx*, have been preserved with the remains of simple feathers covering the body like fur, promoting some scientists to suggest that *Compsognathus* might have been feathered in a similar way. Consequently, many depictions of *Compsognathus* show them with coverings of downy proto-feathers. However, no feathers or feather-like covering have been preserved with *Compsognathus* fossils, in contrast to *Archaeopteryx*, which are found in the same sediments. Karin Peyer, in 2006, reported skin impressions preserved on the side of the tail starting at the 13th tail vertebra. The impressions showed small bumpy tubercles, similar to the scales found on the tail and hind legs of *Juravenator*. Additional scales had in 1901 been reported by Von Huene, in the abdominal region of the German *Compsognathus*, but Ostrom subsequently disproved this interpretation; in 2012 they were by Achim Reisdorf seen as plaques of adipocere, corpse wax.

Like *Compsognathus*, and unlike *Sinosauropteryx*, a patch of fossilized skin from the tail and hindlimb of the possible relative *Juravenator starki* shows mainly scales, though there is some indication that simple feathers were also present in the preserved areas. This may mean that a feather covering was not ubiquitous in this group of dinosaurs, or maybe that some species had fewer feathers than others. they get their bite venom not from real compies but from the Jurassic World Novel version.
