Epichirostenotes was a small theropod dinosaur that lived in what is now Alberta, Canada, approximately 72 million years ago during the Late Cretaceous period. This fascinating creature belonged to a group called oviraptorosaurs, which were feathered theropods known for their distinctive beaked skulls and often elaborate head crests.
Like other oviraptorosaurs, Epichirostenotes was likely covered in feathers and had a toothless beak suited for an omnivorous diet. It would have fed on a varied menu including plants, fruits, eggs, small animals, and possibly shellfish. Its hands were equipped with sharp claws that could have been used for digging, climbing, or handling food.
The discovery of Epichirostenotes has an interesting history - its fossil remains were actually found in 1923 but weren't properly identified as a separate species until 2011. For many years, these bones were thought to belong to another similar dinosaur called Chirostenotes. Only when scientists took a closer look at the specimen did they realise it represented a distinct species, which they named Epichirostenotes curriei in honour of renowned Canadian palaeontologist Philip Currie.
As a relatively small theropod, Epichirostenotes would have been an agile, ground-dwelling creature in the diverse ecosystems of Late Cretaceous Alberta, sharing its environment with much larger dinosaurs like Albertosaurus and various duck-billed dinosaurs.
What made Epichirostenotes distinctive?
Epichirostenotes had the characteristic toothless beak of oviraptorosaurs, along with elongated hands bearing sharp claws. It was likely covered in feathers and had a relatively long neck compared to its compact body.
Behaviour
Epichirostenotes was likely an active forager that used its clawed hands to dig for food and manipulate objects. As an oviraptorosaurian, it may have engaged in elaborate courtship displays using its feathered arms and possibly colourful plumage.
Discovery
Epichirostenotes was first described by Robert M. Sullivan, Steven E. Jasinski and Mark P.A. van Tomme in 2011. The original fossils were discovered at Horseshoe Canyon Formation, Alberta, Canada.
Epichirostenotes FAQ
What did Epichirostenotes eat?
Epichirostenotes was an omnivore with a varied diet. Its toothless beak was well-suited for eating plants, fruits, seeds, eggs, small animals, and possibly shellfish. Like other oviraptorosaurs, it likely used its sharp claws to help process food and dig for buried items like roots or invertebrates.
How big was Epichirostenotes?
Epichirostenotes was a small dinosaur, standing about 1 metre tall at the hip and measuring roughly 2 metres in total length. It weighed approximately 20 kilograms, making it similar in size to a large dog or small pony.
When did Epichirostenotes live?
Epichirostenotes lived during the
Late Cretaceous period, approximately 72 million years ago. This places it in the Campanian stage, relatively close to the end-Cretaceous mass extinction that would occur about 6 million years later.
Where was Epichirostenotes found?
Epichirostenotes was discovered in the Horseshoe Canyon Formation in Alberta, Canada. This fossil-rich formation has yielded many important
Late Cretaceous dinosaur specimens and provides a window into ancient Canadian ecosystems.
How do you pronounce Epichirostenotes?
Epichirostenotes is pronounced 'EP-ih-KYE-roh-sten-OH-teez'. The name can be quite tricky to say at first, but breaking it down into syllables helps: Ep-i-chir-o-sten-o-tes.
What does Epichirostenotes mean?
Epichirostenotes means 'Upon Hand Narrow One' in Greek. This name refers to characteristics of the hand bones that distinguish it from its close relative Chirostenotes, whose name means 'narrow hands'.
How fast could Epichirostenotes run?
The running speed of Epichirostenotes is not well established due to incomplete fossil remains. However, as a small, bipedal theropod with long legs, it was likely quite agile and capable of quick bursts of speed when needed to escape predators or catch prey.
What type of dinosaur was Epichirostenotes?
Epichirostenotes was a theropod dinosaur, specifically an oviraptorosaurian. It belonged to the family Caenagnathidae, which includes several similar beaked, feathered theropods known for their bird-like characteristics and omnivorous diets.
Was Epichirostenotes related to birds?
Yes, Epichirostenotes was closely related to birds. As a theropod dinosaur, particularly an oviraptorosaurian, it was part of the group that gave rise to modern birds. It likely had feathers and shared many anatomical features with early birds, representing an important step in avian evolution.
How many Epichirostenotes fossils have been found?
Epichirostenotes is known from a single incomplete skeleton specimen (ROM 43250) found in 1923. This makes it relatively rare compared to some other dinosaurs, and much about its anatomy and biology must be inferred from related species and the limited remains available.
