CBC Quirks & Quarks: A young carnivorous dinosaur’s last meal
Read more: CBC Quirks & Quarks: A young carnivorous dinosaur’s last mealA fossil has revealed that a juvenile Gorgosaurus fed on smaller bird-like dinosaurs, a diet that’s different from their adult counterparts, Alberta scientists say. (Julius Csotonyi/Royal Tyrrell Museum of Palaeontology) CBC Radio’s Quicks & Quarks podcast has a piece about tyrannosaurs. A juvenile Gorgosaurus, Gorgosaurus libratus, from Alberta, who lived about 75 million years ago, has the remains of its last meal preserved in its abdomen. The research by Royal Tyrrell Museum researchers François Therrien and Darla Zelenitsky was published in the journal Science Advances. Researchers in Alberta uncovered a rare 75 million-year-old fossil of a young dinosaur with bony remains of…

The September 1978 edition of the Field Museum Bulletin had a article by Gordon Baird about his project to survey Mazon Creek fossil localities across Will, Grundy, Livingstone, and Kankakee Counties in Illinois. Almost 300,000 concretions were collected from many, many localities (100+), consisting of 20 strip mines and 90 underground shaft mines. Gordon talks about how he could collect 500 – 1,000 concretions in a day of collecting. The results of the study were published in 1985 in “Biota of a Pennsylvanian muddy…

Read more: ESCONI December 2023 General Meeting – Friday, December 8th, 2023 at 8:00 PM via Zoom – “Ancient Forest Pests: Plant-Insect Interactions in the Fossil Record”The December 8, 2023 General Meeting presentation will be held via Zoom: Michael Donovan, Collections Manager, Paleobotany at the Field Museum will present “Ancient Forest Pests: Plant-Insect Interactions in the Fossil Record”. Description: Plants and insects are the most diverse multicellular organisms on Earth, and their abundant interactions are fundamental components of ecosystems on land. Plant-feeding insects are highly sensitive to environmental disturbances, including past extinction events and climate change. In this talk, I will discuss my research examining how major environmental changes affected ancient insect and plant biodiversity and biogeography, and how those changes have shaped modern ecosystems.

135-Million-Year-Old Footprints Reveal New Dinosaur Species
Read more: 135-Million-Year-Old Footprints Reveal New Dinosaur SpeciesSciNews has a story about a new dinosaur species. The animal, Farlowichnus rapidus, lived about 135 million years ago during the Cretaceous Period. The name Farlowichnus was selected to honor Professor James Farlow, a paleontologist and ichnologist at Purdue University in Indiana. Footprints were found in the Botucatu Formation just outside Sao Paulo, Brazil. The research was published in the journal Cretaceous Research. r. Leonardi and co-authors discovered numerous footprints of the new theropod dinosaur in the Botucatu Formation near Sao Paulo, Brazil. “The sandstones of the Botucatu Formation originally covered a surface estimated in at least 1.3 million km2, the largest…

New study shows ancient Europe was not all forest, half was covered in grassland
Read more: New study shows ancient Europe was not all forest, half was covered in grasslandPalaeoartistic reconstructions of Last Interglacial landscapes in the European temperate forest biome, consistent with our pollen-based estimates of vegetation structure. Credit: Brennan Stokkermans Phys.org has a story about ancient Europe. A recent paper in the journal Science Advances looked at pollen samples from various sites across Europe to determine the distribution of plants during the last inter-glacial period about 116,000 to 129,000 years ago. The researchers from Europe and Canada found that Europe was a temperate forest intermixed with open grasslands. This time interval is before the arrival of modern humans about 40,000 years ago, but Neanderthals were present in…

Paleontology Is Far More Than New Fossil Discoveries: Understanding the ancient past is critical to responding to challenges we face in the future
Read more: Paleontology Is Far More Than New Fossil Discoveries: Understanding the ancient past is critical to responding to challenges we face in the futureRoy Plotnick has a new article over on Medium. It details the importance of Paleontology in the pantheon of science. Paleontology isn’t just fossils and dinosaurs…. it’s critical science needed to understand how the planet has and is changing. In this time of climate change, the knowledge it provides is vital to understanding of where we are and where we’re headed. The focus on fossils, of course, has many potential positive benefits for paleontology. Dinosaurs and other ancient organisms captivate the public, as attested to by films and television shows, such as Prehistoric Planet. The Jurassic Park and Meg franchises would not exist without paleontologists first…

Unraveling the surprisingly complex history of crocodiles
Read more: Unraveling the surprisingly complex history of crocodilesSome ancient crocodiles, like Simosuchus, were doing things vastly different to surviving species, such as eating plants. Credit: Smokeybjb/Wikimedia Commons Phys.org has a story about the history of crocodiles. There are 28 species of living crocodiles, but this represents a small fraction of the the many types that have lived in the past. The ancestors of modern crocodilians likely appeared in North America up to 145 million years ago during the late Jurassic Period. Two recent papers touch on the history of crocodiles. A paper in the journal Royal Society Open Science looks at the ability for crocodiles to tolerate…

PBS Eons: The Huge Extinctions We Are Just Now Discovering
Read more: PBS Eons: The Huge Extinctions We Are Just Now DiscoveringPBS Eons has a new episode. This one is about ocean extinctions during the Silurian Period. It wasn't the quiet time that was once thought. What graptolites tell us is a story of incredible changes in the ocean, of periods where the oceans became poisonous and suffocating before eventually clearing up again. They unlock extinctions and recoveries that scientists didn't see. And, most of all, they show us how unpredictable the Silurian period really could be.
