The I Know Dino podcast is going strong. We have multiple episodes up already, and are working on getting them all transcribed.
You can find our free podcast, with both episodes, on iTunes at:
In our second episode, our featured guest is Dr. Anthony J. Martin, a paleontologist who specializes in ichnology, which according to his website, is “the study of modern and ancient traces caused by animal behavior, such as tracks, trails, burrows, and nests.”
Dr. Martin is also the author of several books, including his most recent one, Dinosaurs Without Bones. You can also find him on Twitter, @Ichnologist. and I recommend reading his post that dissects the ichnology in the Jurassic Park movies.
In this episode, we discuss:
- The dinosaur of the day: Oryctodromeus. The name is Greek for “Burrowing Runner.”
- Oryctodromeus was the first known burrowing dinosaur, and Dr. Martin and his colleagues found an adult and two juveniles in a fossilized chamber, in 2007. They had died and decayed in the burrow, which looked similar to those made by hyenas and puffins.
- Having juveniles with the adults suggests Oryctodromeus provided parental care for an extended period of time.
- Oryctodromeus lived during the Middle Cretaceous, about 95 million years ago, in southwestern Montana and southwestern Idaho.
- Oryctodromeus was up to 6.8 long, and weighed 70 pounds (it was small, but quick)
- Oryctodromeus did not have long arms and legs, like modern burrowing animals. But it did have more specialized adaptations, such as a flexible tail it could curl up underground. This makes it similar to rabbits, aardvarks, and hyenas.
- Dr. Martin recommends visiting Dinosaur State Park in CT to see dinosaur tracks.
- Fun Fact: The largest dinosaur eggs were as big as basketballs. Bigger eggs had thicker shells, so if the eggs had been larger than basketballs, dinosaur babies probably would not have been able to hatch.
