I Know Dino Podcast Show Notes: Nodosaurus (Episode 223)

Episode 223 is all about Nodosaurus, the original member of Nodosauridae: The clade of ankylosaurs without tail clubs.

Interview with Thomas Hopp, scientist, inventor, lecturer, and author. He’s written a number of short stories and novels, including the science fiction series Dinosaur Wars.

Hatching Alamosaurus

He has also proposed that dinosaurs evolved feathers on their hindlimbs to warm their nests. Here are PDFs of his feather paper and his poster from SVP.

The dinosaur of the day: Nodosaurus

  • Ankylosaur that lived in the Late Cretaceous in what is now North America
  • Herbivorous
  • Estimated to be about 13 to 20 ft (4 to 6 m) long
  • Had bony plates on the top of its body, and may have had spikes on the side of its body
  • Bony plates were like bands, alternating between narrow and wide bands over the ribs
  • The wider bands were also covered in bony knobs
  • Had a short neck and a long, stiff tail (no club)
  • Had a small, narrow head, pointed snout, small teeth, and powerful jaws
  • Had five toes on each foot
  • Had powerful forelimbs
  • Named in 1889 by Othniel Charles Marsh (very brief description)
  • Richard Swan Lull gave a more detailed description in 1921
  • Lull also described flat scutes, spines, and plates, though he did not illustrate them
  • Carpenter and Kirkland revisited the description in 1998
  • In 2015, a 4-year-old boy, Wylie Brys found what’s thought to be a Nodosaurus fossil in Mansfield, Texas. He and his father Tim were looking around behind a shopping center. At first they thought it was s turtle fossil. They reached out to Southern Methodist University and worked with them to excavate the area
  • Type species is Nodosaurus textilis
  • Name means “knobbed lizard”
  • Species name refers to the texture near the head (small ossifications in quadrangular form, arranged in rows. Marsh said “The external surface is perculiarly marked by a texture that appears interwoven, like a coarse cloth. This has suggested the species name.”
  • Nodosaurus is the type genus for the nodosaurid group
  • Two groups in Ankylosauria: nodosaurids and ankylosaurids
  • Nodosaurids are usually more primitive, and they don’t have tail clubs, and generally skulls are not as short or broad as ankylosaurids, and the skulls were not covered in scutes
  • Can see Nodosaurus in the Illustrated Encyclopedia of Dinosaurs (a.k.a. Normanpedia), illustrated by John Sibbick in 1889
  • Can also see Nodosaurus in the Land Before Time series (appears in the 3rd movie, as a character named Nod)
  • Can also see Nodosaurus in the game Jurassic World Evoution (unlock via the Hammond Foundation when you complete the Science Division’s mission on Isla Tacaño. Model is based on Borealopelta

Fun Fact: For the tyrannosaur linneage to evolve from Moros interpidus size to T. rex size they would have needed to grow about 4 grams per generation.S

  • UK Police got involved in a dispute between Dinosaur World and the ice cream shop next door over where two Jurassic Park-style Deinonychus should sit
  • Screenrant posted another take on what dinosaurs would have sounded like. Spoiler alert, they don’t roar at you before trying to catch you…
  • MSN listed the “10 coolest dinosaurs” although “10 most popular dinosaurs” is probably more accurate
  • Colin Trevorrow confirmed that Rexy, the iconic Jurassic Park T-rex will return in Jurassic World 2
  • ChillerTV published a list of “13 dynamic dinosaur movies” featuring a lot of top-notch stop motion
  • On April 6, NPR marked the 25th anniversary of Barney the dinosaur; and the apparent solution to a lack of toddler specific television

The dinosaur of the day: Omeisaurus

  • Name means “Omei lizard”
  • Sauropod that lived in the Jurassic in what is now China
  • The name Omei comes from Mount Emei (Omeisaurus was found there, in the Shaximiao Formation of Sichuan Province)
  • Described in 1939 by Yang Zhongjian, also known as C.C. Young
  • More fossils were found in the 1970s and 1980s, which was the “Chinese dinosaur rush”
  • There are six species of Omeisaurus: Omeisaurus junghsiensis, Omeisaurus changshouensis, Omeisaurus fuxiensis, Omeisaurus tianfuensis, Omeisaurus luoquanensis, Omeisaurus maoianus
  • Five of those species (all but Omeisaurus maoianus) were named after the locations where they were found
  • Type species is Omeisaurus junghsiensis
  • Lots of fossils found, so may have been the most common sauropod in the Late Jurassic in China
  • About 66 ft (20.2 m) long and weighed 9.8 tons
  • The smallest species was Omeisaurus fuxiensis, at around 35 ft (11 m) long
  • Had a rounded body, which gave it a small surface area compared to its volume (which would help it stay warm, by reducing heat loss)
  • Had nostrils that faced forward
  • Had a long neck helped it eat foliage, could probably eat one ton of plants a day
  • Omeisaurus tianfuensis had one of the longest sauropod necks (30 ft, or 9.1 m). Mamenchisaurus has a longer neck
  • Mamenchisaurusis thought to have replaced Omeisaurus
  • Scientists used to think Omeisaurus was part of the Mamenchisauridae family, now it’s thought to be part of Euhelopodidae
  • Scientists used to think Omeisaurus had a club tail, based on the club tail fossil being found near Omeisaurus fossils, (which made it hard to figure out which family Omeisaurus belonged in), but now it’s thought to not have a club tail, because a club tail would be too heavy and throw Omeisaurus off balance
  • Other dinosaurs that lived at the same time and place as Omeisaurus included the sauropods Abrosaurus, Dashanpusaurus, Shunosaurus, also the stegosaur Huayangosaurus, the ornithischian Agilisaurus, and predators such as Chuandongocoelurus, Kaijiangosaurus, Gasosaurus, Leshansaurus, Xuanhanosaurus, Yangchuanosaurus
  • Yangchuanosaurus were big enough to be a threat to Omeisaurus
  • Can see Omeisaurus at the Zigong Dinosaur Museum in Zigong, China, and at the Beipei Museum, near Chongqing, in China
  • Euhelopodidae is a family of sauropod dinosaurs, named by Alfred Sherwood Romer in 1956
  • Dinosaurs in this family include Euhelopus, Chiayusaurus, Omeisaurus, Tienshanosaurus

Fun fact: Some momma birds can feed their chicks without stomach acid because they have a special pouch in their esophagus called the “crop.” Dinosaurs may have also used a crop in a similar way, although it is hard to tell since soft tissue rarely fossilizes.
