There was some debate for a while on whether Compsognathus also had feathers or not, since another close relative, Juravenator, had been found with skin impressions that showed scales, not feathers. Found in the jungles of South America, the titan beetle is second only to the Hercules beetle and can grow up to 6.5 inches. 6.5 feet tall, 14 feet long and over 1 ton, it’s estimated he could produce 7,665 Big Macs.

We can see from the fossil record, from the written history of man, and from experience over recent centuries, that many forms of life on this planet have not survived that test. Sometimes, though, inaccuracies in the movies are completely inadvertent. Almost all living organisms can leave fossils, but usually only the hard parts of plants and animals fossilize. But scientifically, such a pairing is as likely as a tiger mating with a giraffe! The TOXODON had supposibly gone extinct at the end of the Pleistocene, nearly 2.6 million years earlier.

Turn a plain styrofoam egg into a dinosaur egg with just a little paint and a lot of imagination. The Diplodocus has a six-meter neck, which suggests a neck of 13.5m for Supersaurus. Time magazine, on April 26, 1993, had a front page cover of a “birdosaur,” now called Mononykus, with feathers (a supposed transitional form between dinosaurs and birds) based on a fossil find that had no feathers. 52 In the same month, Science News had an article suggesting this animal was a digging creature more like a mole. 53 In 1996, newspapers reported a find in China of a reptile fossil that supposedly had feathers. 54 Some of the media reports claimed that, if it were confirmed, it would be “irrefutable evidence that today’s birds evolved from dinosaurs.” One scientist stated, “You can’t come to any conclusion other than that they’re feathers.” 55 However, in 1997 the Academy of Natural Sciences in Philadelphia sent four leading scientists to investigate this find.

The type of collagen an animal has in its bones varies according to its DNA and, in both cases, this collagen was of the same type found in modern chickens and ostriches. [194] The extraction of ancient DNA from dinosaur fossils has been reported on two separate occasions; [195] upon further inspection and peer review, however, neither of these reports could be confirmed. [196] However, a functional peptide involved in the vision of a theoretical dinosaur has been inferred using analytical phylogenetic reconstruction methods on gene sequences of related modern species such as reptiles and birds. [197] In addition, several proteins, including hemoglobin, [198] have putatively been detected in dinosaur fossils. [199] [200] In 2015, researchers reported finding structures similar to blood cells and collagen fibers, preserved in the bone fossils of six Cretaceous dinosaur specimens, which are approximately 75 million years old. [201] [202] The battles that may have occurred between Tyrannosaurus rex and Triceratops are a recurring theme in popular science and dinosaurs' depiction in culture.

We also can’t know what the eyes themselves looked like, although they are major contributors to the appearance of a dinosaur face presented to the public. Bumps, called quill barbs, on the bones mean the dinosaur had feathers -- some Velociraptor specimens have these barbs.

The result of such an impact would be an enormous explosion that would throw dust clouds into the sky, darkening the planet. The oldest and most basal dinosauriforms are found in the Middle Triassic of Argentina ( Novas, 1996 ) and include animals such as Marasuchus ( Sereno & Arcucci, 1994 ) and Pseudolagosuchus ( Arcucci, 1987 ). So, they should be commonly found together in the fossil record, but never are. Stock ones featured include Velociraptor (which gets a focus episode), Oviraptor, Protoceratops, Iguanodon, Ichthyornis, Maiasaura (receives episode focus), Quetzalcoatlus, Edmontosaurus, titanosaurs, dromaeosaurs, troodontids, plesiosaurs, Giganotosaurus, and Tyrannosaurus.

This was triggered, in part, by John Ostrom 's discovery of Deinonychus, an active predator that may have been warm-blooded, in marked contrast to the then-prevailing image of dinosaurs as sluggish and cold-blooded. You'll note I said above that entropy applies in a closed system. Yorick got a fair amount of press as the first monkey to live through a space flight. Numerous other arguments against a biological origin for petroleum exist, such as the claim that hydrogen-saturated hydrocarbons are unlikely to have been derived from any biological debris.
