The dinosaur of the day: Deltadromeus

  • Gabrielle Lyon discovered Deltadromeus in 1995 whereas excavating Cretaceous sediments
  • Paul Sereno and Gabrielle Lyon acquired married in 1996
  • Could also be a junior synonym to Bahariasaurus
  • Bahariasaurus was named in 1934, however the kind specimen was destroyed in WWII, so it’s not doable to check with Deltadromeus
  • Ernst Stromer thought-about a couple of extra specimens to be the identical as Bahariasaurus, however then Paul Sereno referred them to Deltadromeus in 1996. Nevertheless, this has been questioned as a result of they got here from completely different localities within the Bahariya Formation and have some variations from the Deltadromeus

Enjoyable Reality:

Coprolite from herbivores is more durable to seek out than coprolite from carnivores

In line with Paul Barrett, that’s as a result of the there’s calcium in carnivore poop. Particularly, calcium from bones that they ate.

However, herbivore poop is principally the start of a compost pile (partially decomposed vegetation).

This might clarify why the herbivore coprolite with crustacean stays was preserved so nicely.
