Maximucinus muirheadae
Encyclopedia
Maximucinus muirheadae lived during the middle Miocene
and is the largest thylacine
species known to have lived in Australia from the late Oligocene
to the middle Miocene
.
T. muirheadae was a quadrupedal marsupial predator, that in appearance looked similar to a dog with a long snout. Its molar teeth were specialized for carnivory; the cups and crest were reduced or elongated to give the molars a cutting blade. Its estimated weight is 18 kilograms.
The holotype and only specimen is a second upper molar found in Riversleigh
. The species is named after Jeanette Muirhead because of her work on thylacinids.
Miocene
The Miocene is a geological epoch of the Neogene Period and extends from about . The Miocene was named by Sir Charles Lyell. Its name comes from the Greek words and and means "less recent" because it has 18% fewer modern sea invertebrates than the Pliocene. The Miocene follows the Oligocene...
