The earliest fossils known are in the form of stromatolites formed by cyanobacteria about 3.5 billion years ago.
To say however that these are the first life forms is not likely to be correct. Cyanobacteria are already a relatively complex single celled organism. It is likely that simpler forms preceded them but so far no evidence of this has been found.

Dr. Locard was the first Forensic Scientist. His theory was that anytime a person comes into contact with anything, they leave silent evidence that they were there. The suspect of a crime will leave evidence that he was there, and like wise, he will take evidence with him.
Abundant and diverse fossils first appeared in the Cambrian era, although there is fossil evidence throughout much of the Precambrian.
Odelbrecht first advocated the use of photography for the identification of criminals and the documentation of evidence and crime scenes

Physical evidence usually involves objects found at the scene of a crime. Physical evidence may consist of all sorts of prints such as fingerprints, footprints, handprints, DNA material, cut marks, tool marks, etc.Circumstantial evidence is indirect evidence which creates an inference from which a fact may be concluded. For example, circumstantial evidence of a murder is not based on first-hand eyewitness accounts, but may consist of threats that were made, fingerprints left at the crime scene, or the presence of the accused in the vicinity of the crime.

Direct evidence, such as eyewitness testimony, is generally considered more powerful, but successful criminal prosecutions often rely largely on circmstantial evidence, and civil charges are frequently based on circumstantial or indirect evidence. When circumstantial evidence is cumulative, the weakness of such circumstntial evidence is strengthened.Circumstantial evidence is indirect evidence which creates a situation from which a main fact may be inferred. For example; in a murder trial there may not be direct evidence based on first-hand eyewitness accounts of the actual murder itself, but the circumstantial evidence may consist of threats made, fingerprints at the crime scene, or the presence of the accused at, or in the vicinity of, the crime.
The oldest fossilized shark remains that have been found are teeth, identified as the megalodon.
