The dinosaur of the day: Masiakasaurus
- Identify means “vicious lizard”
- Small noasaurid theropod that lived within the Cretaceous in what’s now Madagascar
- Named in 2001 by Scott Sampson, Matthew Carrano, and Catherine Forster
- Kind species is Masiakasaurus knopfleri
- Named after Mark Knopfler, lead singer of Dire Straits, whose music was thought-about to be the expedition crew’s fortunate allure (they had been listening to his songs once they made vital discoveries)
- About 40% of the skeleton was discovered, and included components of the cranium and the tooth, humerus, pubis, hindlimbs, and several other vertebrae
- Extra specimens had been present in 2011, and included the braincase, premxilla, facial bones, ribcage, and extra, and helped scientists be taught extra about noasaurids (Masiakasaurus is now probably the greatest identified noasaurids), Now 65% of the skeleton is understood
- A number of specimens from thirty localities had been present in Madagascar
- A part of the superfamiliy Abelisauroidea and the clade noasaurid, a bunch of small theropods
- Bipedal, with forelimbs that had been shorter than hindlimbs
- About 6.6 ft (2 m) lengthy
- Weighed about 80 lb (35 kg)
- A 2013 examine of Masiakasaurus discovered that it took 8-10 years to develop, and have become the dimensions of a giant canine (progress price is 40% slower than related sized non-avian theropods). However the gradual progress meant it didn’t need to eat as a lot meals, which helped in a semiarid setting with dry seasons and brief provides of meals
- Lengthy, lengthy cranium
- Had a slender neck
- Had 4 fingers on every hand, although the 4 digit was diminished, and had stout, not very sharp, claws
- Initially, the hand bones had been considered foot bones (so scientists initially thought it had a sickle claw on its second toe), however now it’s thought-about to be a finger
- Entrance tooth projected ahead as an alternative of straight down, (completely different from different theropods)
- Had heterodont tooth (completely different shapes alongside the jaw)
- It’s decrease entrance tooth are practically horizontal, and the angle of its tooth enhance till its fourth tooth (the remainder of the tooth are vertical)
- These entrance horizontal tooth haven’t been seen in different predatory dinosaurs
- Posterior tooth have serrations and are recurved
- Entrance tooth had been good for greedy small prey, however not good for tearing massive meals aside (again tooth had been higher for reducing and slicing)
- In all probability had a specialised weight loss program (fish and small prey)
- Different animals that lived in the identical time and place embrace Majungasaurus, Rapetosaurus, Rahonavis
- Majungasaurus might have preyed upon Masiakasaurus (based mostly on one specimen discovered with holes that appear like puncture marks from being hunted or scavenged, although it might even have been an an infection)
Enjoyable reality:
The title “fossil gas” is mostly a misnomer. The formation of oil & coal is totally completely different than fossilization.
The prevailing idea for the way crude oil fashioned goes:
- Enormous numbers of useless plankton, algae, and the occasional different plant or animal fall to the underside of the ocean
- A few of them get buried earlier than they decompose (type of like fossilization)
- Excessive stress and warmth convert them into oil (in no way like fossilization)
When you’re questioning what number of dinosaurs acquired blended in; As William Thomas, a geologist from the College of Kentucky put it:
“A few of the dinosaurs might have gotten concerned in a few of this…” however he thinks “it will be fairly uncommon and a really small and insignificant contribution.”
