A restoration of a Therizinosaurithoides, based on frozen remains of these dinosaurs.
Therizinosaurithoides, also more famously known as the scissorhand (as a common name), is an extinct Pleistocene to Early Holocene herbivorous non-avian Therizinosaur-like theropod dinosaur that lived in what is now Siberia, northern Europe, and North America from 250,000 years ago to 2,500 years ago. They fed on wide varieties of leaves that were present in where scissorhands lived in, including pines, oaks, spruce, redwood, birch, and other types of tree leaves. They were about 45 feet long and weighed 7 tons when they were fully grown. They were probably social animals as some fossil remains and preserved carrion suggests. They most likely went extinct due to climate change brought on due to warming caused by some volcanic eruptions, but thanks to preserved remains, paleontologists studied its genes and DNA and confirmed that it was a Troodont and its closest living relatives are Asian wounders, bringing up hopes to bring back scissorhands from extinction.
