The Crowned Dragon That Never Was – Agathaumas

Paleontology sucks a little sometimes because of just how generally awful the fossil record is. By that, I mean that the fossil record has a bias and only a fraction of all life that has ever lived or died, for that matter, has become fossilized and survived the millions of years as a fossil for us to find them. That being said, the fossil record is still far better than one might suspect. So, most of the time extinct taxa are known from only one specimen. Another is never found ever again. However, there are a few that have continued to crop up in various rock layers as more and more work is done on those layers. The giant dinosaurs were no exception, and there are now over a handful of individual specimens known from several dinosaur genera, and even species – Diplodocus, Apatosaurus, Allosaurus, Stegosaurus, Pachyrhinosaurus, Edmontosaurus, and many more are known from so many specimens that growth stages, sexual dimorphism, individual variation, pathology, and much more can be understood or entirely solved. Two of my favorite examples of this sort of cosmic luck, are Tyrannosaurus and Triceratops. __________________________________________________________________ ✅ PATREON ✅ ✅ STICKERS & SHIRTS ✅ ✅Facebook: ✅Twitter: ✅Instagram: @edgeonthetrail ✅ MUSIC ✅ “Animal Planet’s The Most Extreme - Intro Theme” - PastEonsProductions “Storage Cellar” - Daniel Firdell, Sven Lindvall “Early Avril” - Unicorn Heads “Swing Time” - Music by Pedro “Busy Carmen” - NaumanniBeats “Dude, Where’s My Horse” - Nat Keefe with The Bow Ties “The Colonel” - Zachariah Hickman “Moving On” - Wayne Jones “Nine Lives” - Unicorn Heads “Nanosaur 2 Main Theme” __________________________________________________________________ If I’ve used something on my video that you don’t want me to use, PLEASE EMAIL ME first before flagging a video, I’m very reasonable and will take the video down to replace whatever image or video belongs to you.
