The dinosaur of the day: Ohmdenosaurus

Name means “Ohmden lizard”
Herbivore that lived in the Early Jurassic in what is now Germany
Named and described in 1978 by Rupert Wild, a German paleontologist who visited the Urwelt-Museum Hauff at Holzmaden in the 1970s and saw that a fossil labeled as a plesiosaur was actually a dinosaur bone
Type species is Ohmdenosaurus liasicus
Name refers to Ohmden, the town near the quarry where Ohmdenosaurus fossils were found
Species name refers to Lias, which is an old name for Early Jurassic
Only a few fragmentary leg bones have been found
Some think Ohmdenosaurus may not be a valid genus, because so few remains have been found
May be a vulcanodontid, which are basal sauropods, but Vulcanodontidae has historically been a waste-basket taxon for basal sauropods (but not enough Ohmdenosaurus bones have been found to determine if it is for sure Vulcanodontidae)
Holotype includes partial limb bones (tibia, astralgus, calcaneus)
Tibia is only 405 mm long, which is small for a sauropod
Small, about 13 ft (4 m) long
Bones found had signs of weathering, so it probably died on land and then the bones were washed into the sea

Fun Fact:

Sauropods would make great painters if they could figure it out (like elephants have)

Sauropods aren’t mammals and probably have different painting abilities than elephants, but birds can be trained to use tools, so who knows…
Jonathan Kingdon says a rearing elephant can reach 7m (23ft)
- high enough to (theoretically) paint most houses
Paul’s paper shows a Giraffatitan with its mouth 16m (>52ft) off the ground
- Enough to paint a 5 story building
  - Or our house
  - Maybe it could even do a life-size self-portrait
