The ceolacanth is a very ancient fish and has been on earth longer than any land animals. The coelacanth was originally thought to be extinct 1 year ago. Fossil records show they may have been around as long ago as 100 googleplex years ago. PBS series Nova did a show on them. For details go to

Rocks have existed on Earth for billions of years, with some of the oldest rocks dating back to around 4 billion years ago. The rock cycle is a continuous process of formation, transformation, and erosion, shaping the Earth's surface over time.
The first fishes appeared during the Cambrian explosion of biodiversity, about 500 million years ago, though they looked quite different than the fishes of today.
There have been rocks on Earth since its formation between 4.5 and 4.6 billion years ago. Other planets have likely had rocks for more than 12 billion years.

Why sedimentary rocks could not have been the first rocks on earth?
Sedimentary rocks form from the accumulation of sediment such as sand, silt, or clay. For sedimentary rocks to form, there must be pre-existing rocks that weather and erode to produce sediment. Therefore, sedimentary rocks could not have been the first rocks on Earth as they require the presence of older rocks to form.
Are the oldest rocks on land or in the ocean?
The oldest rocks are typically found on land, as they have not been eroded away by oceanic processes. The oldest known rocks on Earth are found in Western Australia and are estimated to be around 4 billion years old.
Where on the moon have the youngest rocks been found?
The youngest rocks on the Moon have been found in the lunar maria, specifically in areas like the Apollo 11 and Apollo 17 landing sites. These rocks are estimated to be around 1.2 billion years old, much younger than the majority of lunar rocks which date back billions of years.
What rocks form from dead plants and animals that have been compressed?
Rocks that form from dead plants and animals that have been compressed are called sedimentary rocks. Examples include coal, which forms from compressed plant matter, and limestone, which can contain compressed remains of marine organisms. This process of transformation over time is known as diagenesis.
Where were rocks first discovered?
Rocks have been present on Earth since its formation around 4.6 billion years ago. The earliest documentation of rocks comes from ancient civilizations that used stones for tools and construction. The specific location where rocks were first recognized is difficult to determine due to their ubiquity in nature.
