In our 122nd episode, we had the pleasure of talking with Dr. Thomas Hegna, Assistant Professor at Western Illinois College, who makes a speciality of invertebrates, particularly arthropods; and Robert Johnson, Curator of the Geology Museum at WIU, and the artist who makes superior dinosaur 3D prints look similar to genuine fossils.

Episode 122 can be about Lourinhanosaurus, a theropod that lived within the Jurassic in what’s now Portugal.

The dinosaur of the day: Lourinhanosaurus

  • Title means Lourinhã [Formation] lizard
  • Theropod that lived within the Jurassic in what’s now Portugal
  • Found in 1982 close to Lourinhã, Portugal
  • Described in 1998 by Octávio Mateus
  • Sort species is Lourinhanosaurus antunesi
  • Species named in honor of Miguel Telles Antunes, a Portuguese paleontologist
  • Holotype is a partial skeleton, with vertebrae from the ribs, the best tibia and fibula, a metatarsus, and 32 related gastroliths
  • Holotype was a sub-adult
  • About 15 ft (4.5 m) lengthy and weighed about 350 lb (160 kg). Estimated that it will take 10 years to achieve grownup measurement, and an grownup could be 26 ft or 8 m lengthy
  • No actual settlement on the place Lourinhanosaurus belongs. At first it was regarded as a part of Allosauroidea, however now some scientists assume it was a part of Megalosauroidea. In 2010, Benson mentioned it was a part of Sinraptoridae, and in 2012 Carrano mentioned it was a coelurosaur
  • If Lourinhanosaurus is a sinraptorid, it will be the primary one discovered exterior of China
  • In 1993, about 100 eggs (some with embryonic bones) had been discovered at a close-by seaside, Paimogo. In 2001, they had been assigned to Lourinhanosaurus
  • Eggs discovered had been about 5 in (13 cm) lengthy, and regarded as Lourinhanosaurus as a result of they had been discovered close to the sort specimen
  • Can see Lourinhanosaurus and the eggs on the Museu da Lourinhã
  • Carnivorous
  • First identified theropod to have gastroliths, and scientists decided they weren’t swallowed by chance when consuming an herbivorous dinosaur
  • Gastroliths could have helped tenderize meat (carnivorous dinosaurs not nice at chewing), or Lourinhanosaurus could have eaten shellfish and crustaceans and the gastroliths helped crack the shells (unclear if that’s what occurred, since no cranium was discovered)
  • Europe within the Jurassic had many islands, so animals could have tailored to completely different sorts of meals
  • It’s additionally doable that Lourinhanosaurus modified what it ate because it grew older (like how tyrannosaurs are sooner and extra agile and chase smaller ornithopods, after which once they get greater and older, they go for bigger dinosaurs)
  • As a juvenile, it’s doable Lourinhanosaurus went to seashores to eat smaller dinosaurs or eat fish and crustaceans from tidal swimming pools (after which swallowed gastroliths to assist digest them). Then as an grownup, it could have began looking bigger dinosaurs for meals

Enjoyable reality: We will decide the age of dinosaurs by counting Traces of Arrested Progress (LAGs) in bones. It’s much like counting tree rings. We infer that development slows down simply every year from comparisons to trendy animals (like crocodiles).
