Soft Tissue Shows Jurassic Ichthyosaur Was Warm-Blooded, Had Blubber and Camouflage
Soft-tissue analysis of Jurassic ichthyosaur reveals they were most likely warm-blooded, had insulating blubber and camouflage coloration.
Keratin, Pigment, Proteins From 54 Million-Year-Old Sea Turtle Show Survival Trait Evolution
Fossil tissues show that a pigment-based survival trait common to modern sea turtles evolved at least 54 million years ago.
80-Million-Year-Old Dinosaur Collagen Confirmed
Researchers have isolated additional collagen peptides from an 80-million-year-old Brachylophosaurus.

Researchers have found evidence of original keratin and melanosome preservation in a 130-million-year-old Eoconfuciusornis specimen.
Original Dinosaur Claw Sheath Proteins Preserved for 75 Million Years
Researchers find original proteins in a 75 million-year-old dinosaur's claw sheath.
Outrageous Heads Led to Outrageously Large Dinosaurs
Bling and big bods: theropod dinosaurs with bony crests, horns and knobs on their heads got bigger faster than their unornamented brethren.
What Do We Really Know About Dino DNA?
Paleontologist Mary Schweitzer explains what we really know about dinosaur DNA.
Pregnant T. Rex Could Aid in Dino Sex-Typing
Pregnant T. rex could help paleontologists figure out gender of other meat-eating dinos
Researchers Confirm Original Blood Vessels in 80 Million-Year-Old Fossil
Researchers confirm that blood vessel-like structures in an 80 million-year-old hadrosaur fossil are original blood vessels, not biofilms or other contaminants.
True Colors: Using Molecular Analysis to Clarify Dino Color Claims
Paleontologist Mary Schweitzer wants to see colleagues use of molecular analysis and other technologically advanced tools to confirm claims about dino color.
Tail as Old as Time: How Ankylosaur Tail Evolved
How did the ankylosaur get its tail club? Researchers traced the evolution of the ankylosaur’s distinctive tail, finding that the handle arrived first on the scene, and the knot at the end of the tail followed.
Cretaceous Cold Case No. 5: When Evidence Dries Up
This is the fifth post in a series called “Cretaceous Cold Cases” in which the science of taphonomy, or prehistoric forensics, is explained by fascinating cases from the files of Terry “Bucky” Gates, a research scientist with NC State and […]
This Is What Science Looks Like at NC State: Alison Moyer
Editor’s note: This post comes from Alison Moyer, a Ph.D. student in paleontology at NC State. The post is part of an ongoing series that we hope will highlight the diversity of researchers in science, technology, engineering and mathematics. The […]
Pigment or Bacteria? Researchers Re-examine the Idea of ‘Color’ in Fossil Feathers
Paleontologists studying fossilized feathers have proposed that the shapes of certain microscopic structures inside the feathers can tell us the color of ancient birds. But new research from North Carolina State University demonstrates that it is not yet possible to […]
Iron Preserves, Hides Ancient Tissues in Fossilized Remains
New research from North Carolina State University shows that iron may play a role in preserving ancient tissues within dinosaur fossils, but also may hide them from detection. The finding could open the door to the recovery of more ancient […]
