Dinosaur of the Day #247 - Compsognathus Gen 2

The Lost World

Despite its diminutive size Compsognathus is one of the dinosaurs that are best known to science.‭ ‬Not only was the skeleton well persevered but the remains of its last meal,‭ ‬a small lizard named Bavarisaurus were also found inside the specimen proving without doubt that Compsognathus was a carnivore.‭ ‬At the time of its discovery Compsognathus was the smallest dinosaur known to the still new science of palaeontology resulting in the frequent comparison of Compsognathus being the size of a chicken‭ (‬although one meter long about half that length is tail‭)‬.‭ ‬However Compsognathus no longer carries the title of smallest dinosaur as the discovery of maniraptorian dinosaurs like Microraptor has shown that dinosaurs were capable of being very small,‭ ‬and further discoveries are likely to reduce this size even further.

The holotype specimen of Compsognathus was of a juvenile individual meaning that the full size of Compsognathus was not realised until the discovery of a French specimen in‭ ‬1971.‭ ‬Initially hailed as a second species,‭ ‬further study revealed it to be the adult form of the juvenile German holotype.‭ ‬This realisation increased the known length of Compsognathus from eighty-nine centimetres to one hundred and twenty-five centimetres.

Most early reconstructions of Compsognathus show it‭ ‬to have two fingers similar to Tyrannosaurus however these are based upon a product of incomplete preservation.‭ ‬Compsognathus did indeed have a third finger like many other theropod dinosaurs,‭ ‬something that is becoming increasingly‭ ‬well-known with accurate modern reconstructions showing Compsognathus to have three fingers.

The main prey of Compsognathus appears to have been small lizards as evidenced by the remains of fossilised prey in both specimens.‭ ‬These lizards are found in a relatively complete state suggesting that they were not pulled apart but swallowed whole.‭ ‬Invertebrates like insects may have also formed a part its diet,‭ ‬especially in smaller juveniles that were not yet large enough to swallow whole lizards.‭ ‬Also,‭ ‬well preserved fossils of the related Sinosauropteryx show that small mammals may also have formed a part of the diet of Compsognathus.

Compsognathus was well adapted to catching small and presumably fast moving prey like lizards that would have scurried into the undergrowth as soon as they were seen.‭ ‬The long legs that featured a proportionately small humerus when compared to the lower legs are a hall mark of a fast runner.‭ ‬The feet of Compsognathus were also digitigrade meaning that Compsognathus essentially balanced on its toes rather than the flat of its foot.‭ ‬This also means that the main foot bones served to extend the length of the leg and increase the striding length even further.‭ ‬A fast running animal would also explain the very long tail of Compsognathus.‭ ‬Held erect off the ground,‭ ‬the tail would have been a versatile balancing aid when chasing after prey.

The large eyes of Compsognathus suggest that it was a visually orientated predator that may have reacted more to the movement of prey.‭ ‬This would have required fast reflexes to stop prey from escaping,‭ ‬but aside from being a fast runner,‭ ‬the long neck of Compsognathus meant that it could quickly move its head to the sides without moving its body.‭ ‬Compsognathus would also be able to work its head into the undergrowth and pull out prey that was using it for cover.

Compsognathus has a long standing association with Archaeopteryx due to their shared presence in the same deposit,‭ ‬as well as stark similarities which include a specimen that was thought to belong to Compsognathus being revealed to be an Archaeopteryx without the feather preservation.‭ ‬For a long time the question of‭ ‬‘if Compsognathus had‭ ‬feathers‭?’ ‬has been asked by many.‭ ‬Chinese relatives of Compsognathus such as Sinocalliopteryx and Sinosauropteryx show a covering of primitive feathers,‭ ‬different from those seen in modern birds but enough to provide insulation as well as possibly serve a display purpose.‭ ‬The discovery of Juravenator,‭ ‬also from Germany was initially hailed as a relative to Compsognathus that seemed to confirm a lack of protofeathers as evidenced by a skin impression.‭ ‬However a review of Juravenator by Xu Xing in‭ ‬2010‭ ‬revealed a very light covering of protofeathers in the skin impression that are visible under ultraviolet light.‭ ‬These pieces of evidence combine to the suggestion that it is at least possible that Compsognathus had primitive feathers,‭ ‬something which might one day be confirmed by directly attributable fossil evidence.

Eggs that are ten millimetres long were once thought to have possibly belonged to Compsognathus on the basis that they were found in close proximity to Compsognathus remains.‭ ‬However these are no longer thought to have belonged to Compsognathus on the principals that they were not found inside Compsognathus,‭ ‬and that the related and similarly sized Sinosauropteryx had eggs preserved in its oviducts that were much larger at thirty-six by twenty-six millimetres long.‭

Looking at Compsognathus Gen 2’s stats, they are not too dissimilar to their Epic sisters and in regards to health and speed, are slightly better. There isn’t a lot different between them. However, they have a very different mix of abilities. Compsognathus Gen 2 seems to be less a debuff creature and more just a dedicated nuisance. Probably handy for the low end of the Arena but for now, I’m not so sure they will much use beyond that. Perhaps in concert with other swap-in creatures like the Ceratopsians, they might find a small niche.

I think Compsognathus Gen 2 will be of use in the Arena up to a point but I can’t see that ability set making them all that desirable in tournaments and Raids are right out.

What are your thoughts on Compsognathus Gen 2?

I do like rhe compy gen 2. And i just unlocked compy gen 1 by the strike event


Thanks to @Cheeseeater. He helped me with a useful tip and the second try i just BEAT the dinosaurs of the strike. Thanks also for your help @Cheeseeater :slight_smile:


Compsognathus gen 1 is flat out the best of the bunch of flock birds in my opinion, with the unique coming in close second. I run a swap in team and this new bird (The epic one & possibly the rare one if they fix it’s current alert bug it’s only alert at 1/3 hp instead of 2/3) is going to be on my team, damn i’m at 5k trophies and i’m running an unboosted lvl 15 and it’s not doing too bad!

The hit and run on the rare makes it so valuable as well as it’s instant damage move. The epic can be swapped in whilst 2/3 goes to 3/3 and takes a hit (it cloakes that turn so may not even go down to 2/3! worst case scenario it then hits with it’s recovery move and one of them dies (Still at 2/3!) and then can get another hit off dropping to 1/3 and then you swap him out for later!! if you were lucky enough for one of the birds to survive the dodge when swapped in he swaps out at 2/3 which is exactly where he was when he came in.

If you manage to bring them in with a swap move then it only gets better as it saves a hit on one of your team members. Being slow doesn’t even matter because they can’t kill you, counter attackers get distracted. rend is reduced and they can’t be stunned.

If your opponent can’t do 1/3 of their hp through cloak when you swap them in they leave with the same HP it’s bonkers. Free damage.
