The dinosaur of the day: Minotaurasaurus
- Ankylosaur that lived within the Overdue Cretaceous in what’s now Mongolia (Djadochta Formation)
- Medium sized, estimated to be virtually 14 feet (over 4 m) lengthy, even though will have grown, for the reason that sort specimen isn’t totally grown
- In response to its shut kin, had a barrel-like frame, and quick, stocky legs and arms
- Would have walked on all fours, with its frame low to the bottom
- Bring to mind Ankylosaurus, however possibly spikier (and smaller)
- More than likely used to be lined in armor, or osteoderms
- More than likely had a tail membership
- Had a triangle-shaped cranium
- Had a small, extensive cranium this is decrease and wider than its relative Tarchia
- Cranium had a “bull-like look with flaring nostrils”
- Had pyramid-shaped ornamentation at the cranium
- Had horns on the finish of the cranium
- Had a beak
- Had leaf-shaped tooth
- Described in 2009 by way of Clifford Miles and Clark Miles (brothers)
- Holotype is a cranium
- Sort and simplest species is Minotaurasaurus ramachandrani
- Genus title Minotaurasaurus way “Minos-bull reptile”
- Genus title from the Greek mythological creature the Minotaur, which had the top and tail of a bull and the frame of a person
- Refers back to the cranium taking a look like a bull cranium
- Species title ramachandrani is in honor of Vilaynur. S. Ramachandran, who purchased the kind specimen. In step with the paper: “paleontology patron who made positive that this cranium used to be described and made to be had to science”
- Fossil purchased on the Tucson Gem, Mineral and Fossil Exhibit in Arizona
- Ramachandran purchased the cranium in 2003 for $10,000 USD
- It seems that, Clifford Miles and Ramachandran have been strolling across the presentations and Miles stated concerning the cranium, “You purchase it, I’ll title it after you”
- Don’t know precisely the place the fossils have been discovered
- Some paleontologists criticized Minotaurasaurus being described, for the reason that fossil will have been taken illegally from Mongolia
- Ramachandran stated he’d go back the fossil if it used to be discovered to were taken illegally
- On the other hand, it’s unclear
- Holotype is on the Victor Valley Museum in California, U.S.
- Identified to be immature according to the osteoderms being unfused
- Did a CT scan and located nodes at the cranium weren’t fused to the outside of the cranium however have been widely made over bone
- In 2013, a poster at SVP used to be a couple of 2nd specimen, discovered by way of the American Museum of Herbal Historical past and the Mongolian Academy of Sciences (from the Djadochta Formation)
- Specimen incorporated a cranium, and a part of the neck part ring
- Referred to Minotaurasaurus according to main points within the ring scale, the osteoderm, and horn at the cranium
- Had proof of insect burrows within the fossils, in a trend simplest observed from the Overdue Cretaceous Gobi localities (Medusa-like trend)
- Debate over whether or not Minotaurasaurus is a synonym to Tarchia
- Intently associated with Tarchia
- Tarchia used to be an ankylosaur that still lived within the Overdue Cretaceous in what’s now Mongolia
- Lined in armor, had spikes on its again
- Identified for having a bigger mind in comparison to different equivalent ankylosaurs
- Cranium is also very similar to Saichania
- Saichania used to be an ankylosaur that lived within the Overdue Cretaceous in what’s now Mongolia and China
- Saichania had a extensive cranium, and cranium used to be lined in osteoderms (best of the snout, higher eye socket rim, horns at the again of the cranium, horns at the cheeks)
- Minotaurasaurus cranium additionally had options observed in Pinacosaurus
- Additionally very similar to the ankylosaur Shanxia, which lived within the Overdue Cretaceous in what’s now China
- Discovered to be a legitimate species in different research, that discovered it had distinctive options that weren’t because of deformation all over fossilization
- A few of its options have been extra flat or extra horizontal, which made it distinctive
- Discovered the vast flaring nostrils have been actual, and no longer from preservation
- Lived in a dry atmosphere
- Different dinosaurs that lived round the similar time and position come with dromaeosaurs like Velociraptor, troodontids like Byronosaurus, halszkaraptorines like Halszkaraptor, oviraptorids like Oviraptor, alvarezsaurids like Shuvuuia, ankylosaurs like Pinacosaurus, ceratopsians like Protoceratops
