Ankylosaurid dinosaurs have modified distal caudal vertebrae (the handle) and large terminal caudal osteoderms (the knob) that together form a tail club.
First-ever CT scans of the early armored dinosaur Pawpawsaurus campbelli reveal that although the Texas dino lacked its cousin's club-tail it had a sharp nose for danger. Pawpawsaurus's hearing wasn't keen, and it lacked the …
Fortner and colleagues used CT scans of dinosaur fossils and modern reptiles to build a detailed 3D model of the T. rex jaw. Unlike previous models, their simulations include bone, tendons and specialized muscles that wrap around …

The oviraptorid dinosaur Citipati osmolskae (Theropoda: Oviraptorosauria) is known from brooding specimens and from MPC 100/978, an excellently preserved specimen with bones that are fully ...
CT scans and an examination of its microscopic structure showed that the "button-shaped protuberance" on the tail vertebrae wasn't just a …
CT scans aren't just for people — they can also be used on dinosaurs. A skull from the Pawpawsaurus was discovered in North Texas in the early '90s. It was recently scanned, allowing scientists to digitally rebuild the dinosaur's brain. Louis Jacobs is a professor of paleontology at SMU and he talks about his research.
Methodology/principal findings: Computed tomographic (CT) scans of several ankylosaurid tail clubs referred to Dyoplosaurus and Euoplocephalus, combined with measurements of free caudal vertebrae, provide information used to estimate the impact force of tail clubs of various sizes. Ankylosaurid tails are modeled as a series of segments for ...
Scientists have used CT and advanced visualization tools to reconstruct the cranial anatomy of a dinosaur that lived more than 110 million years ago. The team's unusual findings cast new light on the dinosaur's feeding function and habits, and led to a featured magazine spread in the December 2007 "Bizarre Dinosaurs" issue of National Geographic.
The Badlands Dinosaur Museum and CHI St. Alexius Health, both in North Dakota, are preparing to utilize CT imaging on fossils in hopes of uncovering more information about the way dinosaurs walked, roared and lived. The collaboration will allow for scans of delicate fossils that are hard to examine and could yet yield new scientific information.
the base of the flexible tail had attachments for strong muscles the outside bone on the club was more dense end of tail was rigid with overlapping vertebrae. ... many dinosaurs had elaborate nasal passageways that could have served the same function. 38 of 71. ... indicated by CT scans of ankylosauria and pachycephalosauria?
Scientists have discovered 243-million-year-old fossils of dinosaurs' closest relatives, pushing back the origin of dinosaurs by at least 10 million years. The dinosaur-like creature ...
But the blockbuster discoveries were dinosaurs from the late Jurassic, including bones from the spike-backed stegosaur Kentrosaurus, the nearly-20-foot-long Elaphrosaurus, giant bone beds of the running dinosaur Dysalotosaurus and the sauropod Giraffatitan brancai (formerly classified as a Brachiosaurus), which once held the title for largest ...

A mere 200 million years ago, the South African dinosaur Massospondylus walked the earth—and now, thanks to modern CT imaging, researchers have a better understanding of the Jurassic giant. CT scans are giving new life to dinosaurs
The lifestyle of spinosaurid dinosaurs has been a topic of lively debate ever since the unveiling of important new skeletal parts for Spinosaurus aegyptiacus in 2014 and 2020.
Tyrannosaurus rex – Hunter or Scavenger Debate Reignited after Fossil Find Almost ever since T. rex was formally named and described back in 1905, debate has raged amongst scientists as to whether this Late Cretaceous dinosaur was an active hunter or primarily a scavenger. The skull of Tyrannosaurus rex is relatively short when compared to an adult …
Tyrannosaurus rex. New research addresses longstanding mystery on the anatomy of the Tyrannosaurus rex jaw. Tyrannosaurus rex dinosaurs chomped through bone by keeping a joint in their lower jaw steady like an alligator, rather than flexible like a snake, according to a study being presented at the American Association for Anatomy annual meeting …
Paleontologists have made use of color spectral Computed Tomography (CT) images to obtain highly detailed images of the fossilized tail of a 66 million year old …
"The CT scans revealed an enlarged nasal cavity compared to dinosaurs other than ankylosaurians. That may have helped Pawpawsaurus bellow out a lower range of vocalizations, improved its sense of smell, and cooled the inflow of air to regulate the temperature of blood flowing into the brain." First CT scans shed light on Pawpawsaurus's ...
CT scan can be very good at showing bone, but MRI can show not only bone but ALSO give good definition of soft tissue structures. Some of the soft tissue structures that show up clearly on MRI include: abscess (which. Tailbone Doctor. For TAILBONE PAIN (Coccyx Pain), NJ, NY, PA, USA, global.
And now scientists have found not one but two different types of tumor on the same bone — the vertebra of a titanosaur, a gigantic long-necked, long-tailed paleo beast, a new study finds.
CT scans showed that knob osteoderms were predominantly cancellous, which would have lowered the rotational inertia of the tail club and made it easier to wield as a …
Micro-CT scans of the mini feathers show they're a "chestnut brown" colour, with a pale-ish under side. Researchers believe the full tail would have been made up of over 25 vertebrae.
Ensconced in a piece of amber roughly the size of a bottle cap, a 99-million-year-old, 1.4-inch section of a dinosaur tail was found by paleontologists in the Hukawng Valley in Kachin State in ...
A knob of bone caps Zuul's tail, forming a sledgehammer-esque weapon intended to break enemy legs.
Combining the imaging data with measurements of the dinosaur's backbone, they determined the Ankylosaurus could swing its tail in a 100 degree lateral arc, and that larger clubs could generate...
Measures of bone compactness in amniote tetrapods of varying lifestyle were used to infer that two spinosaurid dinosaurs (Spinosaurus aegyptiacus, Baryonyx walkeri) were diving "subaqueous ...

fracture bone, then tail clubs were not likely used as weapons. Distributions of stresses provide information on the function of the handle and knob. MATERIALS AND METHODS Computed Tomography Four ankylosaurid tail clubs (Tables 1 and 2) were scanned using computed tomography (CT), to derive three-dimensional models for use in FEA (Fig. 2).
