One claim made by some proponents of human-dinosaur coexistence is that non-avian dinosaur footprints have been found together with human footprints, with one particular site of note being Paluxy River in Texas. The supposed human tracks in the rock have all been identified to consist of dinosaur tracks eroded to an elongated shape and ...
They first appeared in the fossil record around 66 million years ago, soon after the Cretaceous–Paleogene extinction event that eliminated about three-quarters of plant and animal species on Earth, including most dinosaurs. [25] [26] One of the last Plesiadapiformes is Carpolestes simpsoni, having grasping digits but not forward-facing eyes.
First blood-sucking insects (ceratopogonids), rudist bivalves, and cheilostome bryozoans.

Diversity in stegosaurian and theropod dinosaurs. 131 Ma First pine trees. 140 Ma Orb-weaver spiders appear. 135 Ma Rise of ...
The modern human Oase 2 skull (cast depicted), found in Peştera cu Oase, displays archaic traits due to possible hybridization with Neanderthals. [57] The early modern human Oase 1 mandible from Peștera cu Oase (Romania) of 34,000–36,000 14 C years BP presents a mosaic of modern, archaic, and possible Neanderthal features. [58]
Humanoids may also include human-animal hybrids (where each cell has partly human and partly animal genetic contents) and human-animal chimeras (where some cells are human and some cells are animal in origin). [2] Science fiction media frequently present sentient extraterrestrial lifeforms as humanoid as a byproduct of convergent evolution.

The poll, inspired by the release of the new 'Jurassic World' movie, asked, "Do you believe that dinosaurs and humans once lived on the planet at the same time?" Of the 1,000 people who were ...
A model of the hypothetical dinosauroid, Dinosaur Museum, Dorchester The dinosauroid is a hypothetical species created by Dale A. Russell in 1982. Russell theorized that if a dinosaur such as Stenonychosaurus had not perished in the Cretaceous–Paleogene extinction event, its descendants might have evolved to fill the same ecological niche as humans.
