• Paul Sereno’s Fossil Lab moves to Washington Park

    The 6,000 square foot facility will feature fossil preparation space, multipurpose areas for community programs, and tons of specimens collected from Sereno’s worldwide expeditions. Soon, South Side residents won’t have to travel to the Field Museum to see a Tyrannosaurus rex skeleton—there will be one in their own backyard. Paleontologist Paul Sereno’s Fossil Lab at the University of Chicago is moving to the center of the Washington Park Read More.

  • Bones say fish-eating giant stayed in the shallows

    The swimming abilities of the massive predator and fan-favorite, Spinosaurus, have been hotly debated.
    Using CT scans of fossils to make a virtual skeleton and adding flesh to create a model, our most recent publication concludes Spinosaurus did indeed inhabit shorelines with many adaptations for life at water’s edge, but would fail miserably as a fully aquatic, agile underwater predator.

  • Discovering Dinosaurs Adrift in Seas of Sand

    JENGUEBI, NIGER – Seas of sand form the core of the Sahara, the world’s largest desert. Our expedition caravan wound slowly between dunes, probing for terrain hard enough to get us to our end goal —windswept rock with fossils from the youngest part of the dinosaur era on Africa some 90 million years ago. Exposed as isolated patches, the target areas resemble an oceanic island chain, each patch decreasing in size until disappearing altogether under the sand seas.  Read More

  • Unearthing Africa’s giants — and an ancient calamity

    TCHINEKANKARAM, NIGER — One mile long, rising as barren rock no more than 10 feet above a parched plain of patchy grass and thorny acacia, is an area known as Tchinekankaran (chin-kan-karan), or “place of insects” in Tamasheq, the language of Tuareg nomads. True to its name, voracious scorpions wind spiders and praying mantises dueled under our camp lights, but we came for the sea of fossil bones peeking from rocks nearby. Read More

  • Exploring Gadoufaoua, known as ‘the place where camels fear to go’

    Dispatch No. 2 Live from the Field:

    Petrified tree trunks jut from the desert floor, and fossil jaws and bones of nameless beasts peek out from a barren landscape. Nomad legend describes it as “The place where camels fear to go.” Called Gadoufaoua (Ga-doo-fawa) by French geologists who visited in the 1950s, this 100-mile stretch of the Sahara comprises the richest dinosaur beds on the continent.

    NIAMEY, Niger — In secret patches of the south-central Sahara, blankets of sand hide 20 tons of dinosaur bones.

    There are flying reptiles. A creature that resembles an armored dog. Eleven species yet to be identified — all with long necks. They roamed the desert when it was still green, scientists concluded, as far back as 200 million years ago.

  • Geology and paleontology of the Upper Cretaceous Kem Kem Group of eastern Morocco

    Predators abound on land, in the air and in water some 95 million years on the shores of northern Africa —as shown by the abundant fossils in the Kem Kem region. Large herbivores, such as the long-necked sauropod Rebbachisaurus, could have been hunted or scavenged by several large predators. Artwork by Davide Bonadonna.


  • Spinosaurus Revealed

    New fossils of the huge Cretaceous-era predator, Spinosaurus, reveal it adapted to life in water some 95 million years ago, providing the most compelling evidence to date of a dinosaur able to live and hunt in an aquatic environment. An international team based at the University of Chicago built a CT-based digital model of the 50-foot long dinosaur to understand its anatomy and capabilities.
