Dinosaur of the Day #202 - Deinonychus


Artist: Raph04art.

Although Deinonychus was first discovered in‭ ‬1931,‭ ‬it would not be until the‭ ‬1960s with the advent of more discoveries that it would get named and studied in detail.‭ ‬These studies helped lead to one of the most radical ideas put forward in the field of palaeontology‭; ‬at least some of the dinosaurs were warm blooded.‭

Dinosaurs had always been compared to the reptiles of today which are always slow and sluggish until they can warm themselves up by exposing themselves to heat sources such as basking in strong sunlight.‭ ‬Dinosaurs as a whole had always been considered to be‭ ‘‬just big lizards‭’ ‬but smaller Dinosaurs such as Deinonychus were built to be very small and very fast.‭ ‬Such a lifestyle necessitates the need for a faster metabolism.‭ ‬This in turn is better provided for by being warm blooded,‭ ‬which in turn again requires adaptations for conserving body heat.‭ ‬While there is no direct evidence to support the placement of feathers on Deinonychus,‭ ‬it is a member of the dromaeosaur family,‭ ‬whose members through other fossil evidence are‭ ‬accepted to have had feathers.‭ ‬It would actually be very surprising if Deinonychus did not have feathers.‭

When first discovered the skulls of Deinonychus were fragmented and in a state of poor preservation,‭ ‬giving rise to an appearance not unlike Allosaurus.‭ ‬Later,‭ ‬more and better preserved skull material brought in a re-construction that had the skull being similar to that of Dromaeosaurus,‭ ‬yet still not as robust.‭ ‬The palate was strongly vaulted allowing for a narrowing of the snout,‭ ‬which in turn allowed for improved stereoscopic version.‭ ‬This means that Deinonychus had very good depth perception allowing it to gauge distances of prey items with greater accuracy.‭ ‬The jugals on the skull were wide to accommodate the strong biting muscles‭ ‬and it is generally accepted that larger individuals could easily bite through bone.‭ ‬The skull has very large fenestrae,‭ ‬including two in the lower jaw that would line up beneath the orbital fenestra when the mouth was closed.

The tail is constructed in a similar way to other members of its group with each tendon overlapping several vertebrae,‭ ‬making the tail a rigid‭ ‘‬pole‭’ ‬that could only move at the base.‭ ‬This could be used as a counterbalance when running and turning at speed helping to close the gap on prey items before they could run away.‭

Many palaeontologists‭ (‬although not all‭) ‬consider Deinonychus to have hunted in packs.‭ ‬Evidence for this comes from the frequent remains of Deinonychus found around Tenontosaurus fossils.‭ ‬Tenontosaurus is much larger than Deinonychus,‭ ‬and a single animal would have had great difficulty in taking down an adult Tenontosaurus.‭ ‬This has led to the pack hunter theory,‭ ‬although doubters of the theory have claimed it could just be an example of mobbing behaviour,‭ ‬or many Deinonychus scavenging the kill of a larger carnivore.

Deinonychus was well suited for using its forelimbs to grasp onto its prey,‭ ‬but like with Velociraptor,‭ ‬the‭ ‘‬killing claw‭’ ‬on the second toe of each foot seems to be better suited for stabbing than slashing.‭ ‬It could be that the claw was used to stab at a critical spot such as the neck.‭ ‬It may even have been used as a defence against others of its species for territorial defence or in pack domination fights.‭ ‬The only thing that we can be relatively sure of is that the old idea of a Deinonychus slashing open a dinosaurs belly in a single stroke is not very likely.‭ ‬One little thing of note about the claw is that it seems to have been held back so that it did not hit the ground while it was walking.‭ ‬This does prove that Deinonychus did at least have a special purpose for the claw.

Evasive Strike.
High Pounce.

The first of our new species of dinosaur released into the wild is Deinonychus. She is comparable to Velociraptor but with much better health and lower damage. She has the same high pounce but her basic attack grants her a dodge chance - although with the overuse of resilient creatures right now that isn’t so great.I think for now she will do well as a starter dinosaur but unless she gets a hybrid in a future update I feel that is where she will remain.

As with most Common rarity creatures she isn’t going to be of use in Raids but she may be a good tournament option,

What are your thoughts on this new dinosaur?

Not bad but also things like Sarcosuchus and suchomimus are things you can use in raids

It’s like a giant chicken.

Love this dino in general. Haven’t had a chance to test her out yet, though.

No, Haast Eagle has stolen the crown

Deinonychus is honestly, not that good, but looks amazing. Maybe Poukadei next update? :man_shrugging:

Deinonychus is my favorite dinosaur. Has been for a long time. Glad to see he’s in the game, sad to see he’s so useless.

An interesting coincidence is that while Velociraptor has been found with what are assumed to be feathers, no feathers or anything like them have been found associated with Deinonychus. Yet Velociraptor is scaley, and Deinonychus is feathered.

I think it is down to Deinonychus being the poster dinosaur for warm-bloodedness and agile.
