Achillobator, which means Achilles warrior, is a species of large dinosaur of genus dromaeosaurid who lived in Asia during the Late Cretaceous period about 96 million-89 million years ago at Bayan Shireh Formation. Their first remains were found during a Mongolian Russian field expedition in Mongolia in 1989 and were described and named in 1999. They are known to be one of the largest dromaeosaurs with some other dinosaurs named Austroraptor, Dakotaraptor, and Utahraptor.

They were carnivorous dinosaurs and an active feathered predator who hunted with those enlarged sickle-shaped claws on each second toe. One of the notable features of this dinosaur is a robustly built skeleton which is closely related to the trait in the dromaeosaur dinosaur. They differ from the dromaeosaurids in the pelvis, maxilla, femur, and vertically oriented pubis.

Achillobator Interesting Facts

How do you pronounce 'Achillobator'?

Achillobator's name is pronounced as 'a-KIL-o-BAY-tor', which means Achilles hero.

What type of dinosaur was an Achillobator?

Achillobator dinosaurs can be classified in the dromaeosaurid taxon as they are large-sized dromaeosaurids who are mainly habitual to terrestrial habitats instead of arboreal or amphibious. They lived during the late cretaceous period, about 96 million-89 million years ago. In 1989 while exploring the outcrops at the Khongil locality in South Central Mongolia, conducted by the Mongolian and Russian Paleontological Expedition in the Gobi Desert, many fossils of dinosaurs were discovered. Mongolian paleontologist Altangerel Perle and North American paleontologists Mark A Norell and James M. Clark described the Achillobator. They are fast runners and mainly feed on large prey. Dakotaraptor and Achillobator were with those of enlarged sickle-shaped claws on each second toe.

In which geological period did the Achillobator roam the earth?

Achillobator lived during the late cretaceous period about 96 million to 89 million years ago and lived in Asia and whose fossils were found in places such as Dornogovi (Mongolia). They represent the first dromaeosaurid known from the Bayan Shireh Formation.

When did the Achillobator become extinct?

Achillobator became extinct about 96 million-89 million years during the Late Cretaceous period, it was an extinct feathered Achillobator and theropod dinosaur, a relative of modern-day birds.

Where did an Achillobator live?

Achillobator velociraptor, based on its characteristics, lived in terrestrial habitats mostly known to be living in Asia, the velociraptor fossils are known to be found in the Gobi desert and southern Mongolia, and parts of northern China.

What was an Achillobator's habitat?

Achillobator actively roamed in Asia during the late cretaceous period and their fossils were found in Dornogovi (Mongolia) by the Mongolian and Russian Paleontological Expedition in the Gobi Desert between 1989-1999. Actually, the one larger species than these featherless Achillobators was the Utahraptor, which were 20 ft (6.1 m) long.

Who did an Achillobator live with?

Achillobator, meaning Achilles warrior, lived during the Late Cretaceous period. Their remains were found in 1999, and they probably lived in a group of four to five dinosaurs or velociraptors in combination, as they were carnivores, hunting for large size prey alone in or group.

How long did an Achillobator live?

They existed on earth during the Late Cretaceous period, about 96 million-89 million years ago. Their total lifespan, however, is unknown.

How did they reproduce?

Achillobators reproduced by laying eggs. They are believed to have laid between 15-20 eggs per clutch. However, their reproduction details remain unidentified. Achillobator reconstruction was completely like other raptors of this family, which actively included a coat of feathers, underlining their close evolutionary relationship with modern birds. However, they are not based on any fossil evidence.

Achillobator Fun Facts

What did an Achillobator look like?

Achillobators had furry feathers and short legs

Utahraptor, Achillobator sizes are almost the same and measure up to 15-20 ft (4.6-6.1 m) from snout to tail. They are basically known as bipedal carnivores in the pelvis, maxilla, femur and vertically oriented pubis. They had an estimated weight of 551.15–767.20 lb (250-348 kg), they were the second-largest Dromaeosaurus, in comparison with Utahraptors, with a tibial length of 19.29 in (49 cm) or 20 ft (6.1 m). Their metatarsal is quite wide at the upper end and the femur is a bit longer than the tibia. These tall dinosaurs are not famous but one of those from the random one. The remaining hindlimbs,‭ ‬forelimbs,‭ ‬shoulder,‭ ‬ribs,‭ ‬as well as an upper jaw fragment of the premaxilla with teeth partially in the combination. They were with those of enlarged sickle-shaped claw on each second toe and used to live in Dornogovi (Mongolia). Mongolian paleontologist Altangerel Perle and North American paleontologists James M. Jim Clark and Mark A Norell described the Achillobator in detail. The Achillobator skull was similar to the Dromaeosaurus t.

How many bones did an Achillobator have?

They have a lot of bones as they are the second-largest genus of dinosaurs, after Utahraptor with a tibial length of 19.29 in (49 cm). Their close evolutionary relationship was not totally based on fossils. This could be understood by seeing the Achillobator's skeleton.

How did they communicate?

The exact means of their communication process is unknown, but the Achillobator sound was deafening when they hunted in packs.

How big was an Achillobator?

Achillobator's size was probably small in size as compared to the Utahraptor who was 275.59 in (700 cm) in length. Achillobator length is about 196.85 in (500 cm) long and 6 ft (1.82 m) tall, which is 50 times larger than mountain zebras.

How fast could an Achillobator move?

Achillobator speed is quite fast and they also catch their prey while running and hunting. They make their move as fast as they could. They could also run at a speed of about 25 mph (40.23 kph), which is similar to African elephants.

How much did an Achillobator weigh?

As per research by the scientists they weigh around 250–348 kg (551–767 lb), which is 50 times heavier and bigger than an hourglass dolphin. When comparing Achillobator vs Utahraptor they were almost the same size.

What were the male and female names of the species?

According to research, male and female Achillobator are not named with some specific names to describe them separately. Therefore, they are known as male Achillobator and female Achillobator.

What would you call a baby Achillobator?

The baby is also called the same as baby Achillobator or young Achillobator and they are reproduced by laying eggs.

What did they eat?

These carnivores species' diet consists of other animal's meat. They largely fed on large prey, and their diet mainly consisted of meat and other small animals too.

How aggressive were they?

They were a bit aggressive towards large size animals as they were being preyed on by them.

Did you know...

Achillobator was described by Mongolian paleontologist Altangerel Perle and North American paleontologists Mark A Norell and James M. Jim Clark.

Did Achillobator hunt in packs?

Yes, this dinosaur was a pack hunter like the Utahraptor, as they also hunted in packs. Packs of Deinonychus hunted 30 ft (9.14 m) long relatives of the iguanodons and a pack of Utahraptors taking on a 50 ft ( 15.24 m) elephantine sauropod.

How many bones did the Achillobator have in its tail?

They had a long tail and is curved horizontally in a long S shape and were quite flexible.
