Episode 476: Dino Hint Fossils Section 2: Chunk Marks, burrows, scars, and extra. Each and every degree in a dinosaur’s existence left at the back of hint fossils: claw marks from a father or mother excavating a burrow, eggshells left through hatchlings, fossilized digested meals, combat scars, and in the long run, enamel marks left through predators or scavengers.
One of the ichnology subjects we quilt this week:
- Dinosaur bones with punctures, grooves, and scrapes lend a hand to spot their predators (or scavengers)
- Eggs display proof of communal nesting and the mummy’s frame temperature
- A filled-in burrow preserved the dinosaur that was once snoozing within
- Fossilized regurgitate, intestine contents, and feces all let us know about what dinosaurs ate
A few of our favourite assets about ichnology:
- The guide “Hint Fossils: Ideas, Issues, Potentialities” edited through William Miller III supply
- The guide “Hint Fossils as Signs of Sedimentary Environments”, edited through Dirk Knaust and Richard G. Bromley (excellent intro, and contains the historical past of the find out about of ichnofossils) supply
- The guide “Ichnology: Organism-Substrate Interactions in House and Time” through Luis A. Buatois and M. Gabriela Mangano (has a excellent intro on what ichnology is) supply
- The guide “Dinosaurs With out Bones” through Anthony J. Martin (talks in regards to the lines dinosaurs particularly left at the back of, and most probably was once my first advent to ichnology, after I learn the guide once we have been first beginning the podcast—we interviewed Anthony long ago 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, very similar to Camptosaurus
- Gave the impression of different ornithopods
- Walked on two legs, cumbersome frame, lengthy tail, elongated head (in paleoart)
- Unknown how giant it was once
- No distinct options in fossils discovered, looks as if different ornithopods, so thought to be to be a nomen nudum
- Bonebed the place it was once discovered is most commonly ornithopods
- Sort species is Bihariosaurus bauxiticus
- Genus identify method “bihor lizard”
- Bihor County is in Romania
- Named in 1989 through Florian Marinescu (didn’t describe it)
- Marinescu excavated through give up 500 bones from the realm in 1978 to 1979
- Marinescu named Bihariosaurus in response to subject material studied through Patrulius and others (he was once a part of it), who recognized Hypsilophodon and Valdosaurus, Iguanodon and Vectisaurus within the bone assemblage
- Fossils discovered come with lengthy bones of the hand (metapodials), vertebral centra, and phalanges (bones within the hand or toes)
Amusing Reality:
There don’t seem to be simplest fossilized feces (coprolites) but in addition lines of fossilized urine (urolites).
