The skeletal remains of a diminutive mystery dinosaur excavated in Colorado have been relocated to London, England. The designation of these bones, which belong to a newly identified species termed *Enigmacursor mollyborthwickae*, is a component of a sustained initiative aimed at highlighting the importance of smaller groups of fossils.
These specimens were initially found in the Morrison Formation, a region in the United States celebrated for yielding some of the most notable dinosaur fossils. While earlier finds, such as the stegosaurus and allosaurus, have been uncovered here, various smaller species discovered in the vicinity have frequently been ignored. One such neglected set of remains pertains to the newly recognized *Enigmacursor mollyborthwickae*.
One motive for officially naming this dinosaur and showcasing it in London is to raise awareness of additional overlooked specimens from this segment of the US. Although the allosaurus and stegosaurus might garner more fascination, they are certainly not the sole dinosaur remains extracted from Colorado. Indeed, while the larger dinosaur fossils are more awe-inspiring, each fossil we unearth contributes to our understanding of how the world functioned in ancient times when dinosaurs dominated the landscape.
A [new study](https://royalsocietypublishing.org/doi/10.1098/rsos.242195) outlining the remains of the mystery dinosaur has been released in the journal *Royal Society Open Science*. Furthermore, as mentioned earlier, the dinosaur is currently available for public viewing at the Earth Hall Mezzanine in London. According to an analysis of the new species, researchers suspect it existed during the concluding phases of the Late Jurassic Period, approximately 152 to 145 million years ago.
The appearance of the mystery dinosaur indicates that it was likely designed for rapid, swift interactions, allowing it to evade danger with its speed and agility. It was noted by the researchers that it had elongated legs and was roughly the size of a dog. Unfortunately, the method by which the fossil was secured prior to its transfer to the Natural History Museum in London has complicated the determination of its age at the time of its demise.
It is hoped that future discoveries of this species will provide greater insights into these enigmatic dinosaurs and their role while they traversed the Earth. Scientists have also recently [discovered the fossils of another new dinosaur species](https://bgr.com/science/a-new-species-of-dinosaur-was-discovered-sitting-in-a-jar-since-2005/) after it remained in a jar in a museum for several years.
