From UPSC perspective, the following things are important :

Prelims level : Cynodonts

Mains level : NA

The Tiki Formation in Madhya Pradesh, a treasure trove of vertebrate fossils, has now yielded a new species and two genera of cynodonts, small rat-like animals that lived about 220 million years ago.

Tiki Formation

  • The Tiki Formation is a Late Triassic geologic formation in Madhya Pradesh.
  • Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
  • Phytosaur remains attributable to the genus Volcanosuchus have also been found in the Tiki Formation.
  • The genera Tikiodon, Tikitherium and Tikisuchus and species Rewaconodon tikiensis, Hyperodapedon tikiensis and Parvodus tikiensis have been named after the Tiki Formation.

Findings of the new study

  • The fossil teeth were studied for size, crown shape, structure of the cusps and compared with previously reported cynodonts.
  • Cynodonts are important in evolutionary studies as this group ultimately gave rise to the present-day mammals.
  • By studying their molar and premolar teeth, we see how they slowly evolved and modified.
  • Their crown shape shows that these animals are actually intermediate forms that are very near to the mammalian line of evolution.
  • Cynodonts and living mammals both belong to a group of egg-laying vertebrates (amniotes) called synapsids.
  • The close relationship of cynodonts with living mammals is seen in their bones.
