Achillobator giganticus

By Calum O’Halloran at @ridiculouslyphotogenicsinosaurus

Name: Achillobator giganticus 

Name Meaning: Achilles hero 

First Described: 1999

Described By: Perle, Norell & Clark 

ClassificationDinosauria, Theropoda, Neotheropoda, Averostra, Tetanurae, Orionides, Avetheropoda, Coelurosauria, Tyrannoraptora, Maniraptoriformes, Maniraptora, Pennaraptora, Paraves, Eumaniraptora, Dromaeosauroidea, Dromaeosauridae, Eudromaeosauria, Dromaeosaurinae

Achillobator is a fairly famous raptor due to its large size. Like Austroraptor and Utahraptor, it was on the larger end of raptor size, comparable to the raptors of Jurassic Park. In fact, it was about 5 to 6 meters long and 2 meters tall. It was found in the Bayan Shireh Formation in Dornogovi Province, Mongolia. It lived about 90 million years ago, in the Turonian age of the Late Cretaceous. It is only known from very fragmentary remains, however cladistic analyses have proven it is not a chimera (a mixture of different dinosaur fossils). It lived alongside the tyrannosaurid Alectrosaurus which Achillobator probably had to compete with for food. It also lived alongside Segnosaurus, Talarurus, Bactrosaurus, a sauropod, and an azhdarchid pterosaur.

So I have my thesis due on this calendar day and as such I am currently in the middle of pulling an all-nighter (if daylight has broken and I haven’t slept and have no plans of sleeping, does that mean I have successfully pulled the all-nighter? I like to think so… Anywho the moral is that I am tired.) So today’s dinosaur comes early because I need a break from thinking about sexual isolation in the seed beetle Callosobruchus maculatus and how sad it is that the lady at starbucks gave me a small regular hot chocolate rather than the large white mocha that I ASKED FOR. So on to today’s dinosaur. 

Buitreraptor was a smaller dromaeosaur, fairly closely related to Austroraptor. It was about 1.5 meters long and .5 meters high. It was found in the Candeleros Formation, Patagonia, Argentina. It lived from the Cenomanian to the Turonian ages of the Late Cretaceous period, about 94 million years ago. It had a very slim, flat, and long snout, with a lot of very small teeth without serrations or cutting edges. Rather, they were grooved, recurved and flattened. This probably means that it may have been piscivorous, utilizing that snout to feed on fish and other small marine creatures. This skull mimicked its whole body, which was long and slender. The fact that it lived in South America is interesting, as the continent had split from the northern landmasses where other dromaeosaurids are primarily found. Buitreraptor is one of a few southern raptors, who all have similar, different characteristics from their northern relatives. This indicates that Buitreraptor and its relatives were more closely related to each other than their distant, more famous, relatives. It lived alongside very huge animals such as the carcharodontosaurids Giganotosaurus and Mapusaurus, and probably served as their prey.

Euronychodon portucalensis, E. asiaticus

Source: https://en.wikipedia.org/wiki/Euronychodon

Name: Euronychodon portucalensis, E. asiaticus

Name Meaning: European claw tooth

First Described: 1991

Described By: Antunes & Sigogneau-Russell

ClassificationDinosauria, Saurischia, Eusaurischia, Theropoda, Neotheropoda, Averostra, Tetanurae, Orionides, Avetheropoda, Coelurosauria, Tyrannoraptora, Maniraptoriformes, Maniraptora, Pennaraptora, Paraves, Eumaniraptora, Averaptora, Troodontidae

Euronychodon was a tooth taxon troodontid, found in Europe and Asia. E. portucalensis was found in Taveiro, Portugal, dating back to about 70 million years ago in the Maastrichtian age of the Late Cretaceous. E. asiaticus was found in the Bissekty Formation of Uzbekistan, dating to about 92 million years ago, in the Turonian age of the Late Cretaceous. Given that it is only known from teeth, it is unsure whether or not it was a coelurid, an ornithomimosaur, a dromaeosaurid, or a troodontid. The enamel was identical to that of Byronosaurus, a troodontid, hence its current classification. It probably would have been about two meters long and would have been carnivorous or insectivorous.

Name Meaning: Pampas Thief 

First Described: 2011

Described By: Porfiri, Calvo & Santos

ClassificationDinosauria, Saurischia, Eusaurischia, Theropoda, Neotheropoda, Averostra, Tetanurae, Orionides, Avetheropoda, Coelurosauria, Tyrannoraptora, Maniraptoriformes, Maniraptora, Pennaraptora, Paraves, Eumaniraptora, Dromaeosauroidea, Dromaeosauridae

Pamparaptor is a basal dromaeosaurid from the Turonian to Coniacian ages of the Late Cretacoues, about 89 million years ago. It was found in the Portezuelo Formation of the Neuquén Group, Patagonia, Argentina. It was originally named as a juvenile specimen of Neuquenraptor, but has since been named its own genus. It is known from a nearly complete left foot. It was a small raptor, only 5. to .7 meters long.
