Episode 476: Dino Hint Fossils Half 2: Chew Marks, burrows, scars, and extra

Episode 476: Dino Hint Fossils Half 2: Chew Marks, burrows, scars, and extra. Each stage in a dinosaur’s life left behind hint fossils: claw marks from a guardian excavating a burrow, eggshells left by hatchlings, fossilized digested meals, battle scars, and in the end, tooth marks left by predators or scavengers.

Among the ichnology subjects we cowl this week:

  • Dinosaur bones with punctures, grooves, and scrapes assist to establish their predators (or scavengers)
  • Eggs present proof of communal nesting and the mom’s physique temperature
  • A filled-in burrow preserved the dinosaur that was sleeping inside
  • Fossilized regurgitate, intestine contents, and feces all inform us about what dinosaurs ate

A few of our favourite sources about ichnology:

  • The e-book “Hint Fossils: Ideas, Issues, Prospects” edited by William Miller III supply
  • The e-book “Hint Fossils as Indicators of Sedimentary Environments”, edited by Dirk Knaust and Richard G. Bromley (good intro, and contains the historical past of the examine of ichnofossils) supply
  • The e-book “Ichnology: Organism-Substrate Interactions in Area and Time” by Luis A. Buatois and M. Gabriela Mangano (has an excellent intro on what ichnology is) supply
  • The e-book “Dinosaurs With out Bones” by Anthony J. Martin (talks in regards to the traces dinosaurs particularly left behind, and possibly was my first introduction to ichnology, once I learn the e-book after we have been first beginning the podcast—we interviewed Anthony approach again in episode 2, and not too long ago remastered the episode) supply

The dinosaur of the day: Bihariosaurus

  • Ornithopod that lived within the Early Cretaceous in what’s now Romania
  • Iguanodontian, just like Camptosaurus

  • Marinescu named Bihariosaurus based mostly on materials studied by Patrulius and others (he was a part of it), who recognized Hypsilophodon and Valdosaurus, Iguanodon and Vectisaurus within the bone assemblage
  • Fossils discovered embody lengthy bones of the hand (metapodials), vertebral centra, and phalanges (bones within the hand or toes)

Enjoyable Reality:

There aren’t solely fossilized feces (coprolites) but in addition traces of fossilized urine (urolites).
