Kepodatylus (Kepodactylus insperatus) was a flying reptile of the Late Jurassic period, that existed about 145 million years ago. A team from the Denver Museum of Natural History carried out the excavation of the fossils in the Garden Park of Colorado, United States.
The remains included a humerus, a few finger bones, a crushed cervical vertebra, and a metatarsal. These were not enough to get a detailed idea of this creature. However, the paleontologists were able to point them out as pterosaurs and grouped them as a new genus, named Kepodactylus. Due to a lack of adaptive radiation and evolution, these creatures of Colorado succumbed to extinction.
Kepodactylus is pronounced as Kee-po-dac-ty-lus.
Kepodactylus was a flying reptile belonging to the Ctenochasmatidae family, which is under the Pterosauria order. It was not a dinosaur.
These species existed during the Late Jurassic period from Kimmeridgian Age to Tithonian Age. It occurred about 145 million years ago and was the third era of the Jurassic period. It was the time when all the evolved species of reptiles, including sauropods, theropods, and pterosaurs, roamed the Earth.
The Kepodactylus pterosaur became extinct about 145 million years ago due to natural disasters like volcanic eruptions, earthquakes, meteor impacts, and forest fire. A lack of adaptive radiation, followed by a lack of evolution, as well as the larger predatory dinosaur species of that era were also the reasons for their extinction.
The fossils of this extinct genus were excavated from the Garden Park in Colorado in the United States. This was carried out by a team from the Denver Museum of Natural History, who also came across small disarticulated bones of several other animal species in the quarry.
After the various pieces of research, the paleontologists confirmed that the bones were not of a dinosaur, but belonged to an extinct genus of Pterosaur in Colorado. As their diet included fish, it may be assumed that these basal member pterosaurs lived in wetlands and nearby water bodies from where they could catch their prey easily.
Although we don't have sufficient information about the social behavior of this species, researchers claim that most of the pterosaurs nested in groups.
Due to a lack of specimen evidence, we are unable to determine the exact life expectancy of these species. However, several pieces of research conducted by scientists and paleontologists reveal that most of the creatures of the Jurassic period lived for about 60 to 70 years. This included the dinosaur species as well as the pterosaurs.
As this extinct genus of pterosaur was a reptile, it can be deduced that they were egg-laying animals. They probably nested in groups and kept an eye on their eggs. They were quite territorial in nature and protected their juveniles and eggs. Their rounded eggs were amniotic in nature. Research on the pterosaur fossils by the science community provided us the information that the males had smaller pelvises along with a large cranial chest. Females, on the other hand, were devoid of any cranial chest but had large pelvises. Their eggs were soft with a covering of parchment-like shells. These eggs were buried in the ground from where they derived water and other nutrients.
The researchers of the Denver Museum of Natural History, after extensive fieldwork in the Morrison Formation of Colorado and research on the retrieved fossil pieces, described the species as a flying reptile. The remains retrieved included a single crushed caudal vertebra, few finger bones, only the left humerus along a single metatarsal. Although the bones were heavily damaged, researchers were able to conclude that these creatures belonged to the pterosaur clade and grouped them as a separate genus named Kepodactylus. They had large and sharp beak with a huge wingspan. There were not very colorful.

Only a single specimen of Kepodactylus is excavated till now, which does not provide sufficient information on the total number of bones they had. The fossils retrieved included a single cervical vertebra, a few wing finger bones, the left humerus, and a single metatarsal. Although the cervical vertebra was heavily damaged, researchers were able to find extensive similarities with those of the Pterodactylus.
The mode of communication was both vocally and visually. They were able to produce low grunts and other similar sounds. They may have also engaged in duels and displayed numerous wing and tail movements.
Unfortunately, the scanty fossil evidence did not provide us any information on the size of these species of the extinct genus. However, the wingspan of these creatures is known, which is about 8.3 ft (2.5 m). This was bigger than the wingspan of Nemicolopterus crypticus, which was only 10 in (25 cm).
Although the exact speed with which these Kepodactylus creatures flew is unknown, we do know that pterosaurs had an average speed of 56 mph (90 kph). The pycnofibers present on their skin developed into feathers and other hair-like structures, that helped the creature to glide and drift in the air. They used their head to navigate during flight.
The weight of these creatures from Colorado is not known.
The science communities have not provided any names to the male and female species of the Kepodactylus pterosaurs of the Jurassic period.
A baby Kepodactylus can be called a hatchling or a nestling, owing to the fact that they were egg-laying animals.
These pterosaurs of the genus Kepodactylus from Colorado ate an array of fish. They were primarily piscivores. Their long protruded mouth helped them to capture their prey easily from the shallow water bodies.
As these were flying reptiles with small bodies, we can assume that these creatures were moderately aggressive and intelligent. Also, they were territorial in nature and may have engaged in duels with other dinosaur species or animals of their kind.
The name of the genus Kepodactylus is derived from the Greek words, 'kepos' meaning 'garden' and 'daktylos' meaning 'fingers'. The term Kepos referred to the Garden Park of Colorado from where the remains of this creature were excavated, and the term 'daktylos' referred to the characteristic finger-like bones of this pterosaur.
