Previously the earliest was Eomaia, a crown group mammal from about 125M years ago. It had aquatic adaptations including flattened tail bones and remnants of soft tissue between the toes of the back feet, suggesting that they were webbed. Previously the earliest known semi-aquatic mammaliaforms were from the Eocene, about 110M years later.

Geoduck, a species of saltwater clam native to the Puget Sound, have been known to live more than 160 years. [88] [89] A Swedish man claimed that a European eel named Åle was 155 years old when it died in 2014. If correct, it would have been the world's oldest, having been hatched in 1859. [90]
The animal’s fossil records date back 225 million years, predating the previously confirmed first mammal by approximately 20 million years.
Palaeontologists analysed fossil remains showing a small, feathered dinosaur – known as Microraptor – with the foot of an animal inside its ribcage.
The earliest known catarrhine is Kamoyapithecus from uppermost Oligocene at Eragaleit in the northern Kenya Rift Valley, dated to 24 million years ago. [7] Its ancestry is thought to be species related to Aegyptopithecus , Propliopithecus , and Parapithecus from the Faiyum depression, at around 35 million years ago. [ 8 ]
The oldest fossil evidence for paravians — the dinosaur group that includes the earliest birds and their closest relatives — appears around the middle of the Jurassic Period (201.3 million to ...
From its earliest appearance at about 1.9 Ma, H. erectus is distributed in East Africa and Southwest Asia (Homo georgicus). H. erectus is the first known species to develop control of fire, by about 1.5 Ma. H. erectus later migrates throughout Eurasia, reaching Southeast Asia by 0.7 Ma. It is described in a number of subspecies. [38]
