What is the difference between direct dating and indirect dating in archaeology. Are you sure you want to delete this answer. Direct dating is when you date an object by taking a sample of itself and doing carbon dating on it for example. Indirect dating is something like stratigraphic dating where you date the strata above and below the object or artifact and get a timeframe that you can place the object in.
Chronological datingor simply datingis the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology. This usually requires what is commonly known as a "dating method". Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, historyarchaeologygeologypaleontologyastronomy and even forensic sciencesince in the latter it is sometimes necessary to investigate the moment in the past in which the death of a cadaver occurred. Dating methods are most commonly classified following two criteria: Relative dating methods are unable to determine the absolute age of an object or event, but can determine the impossibility of a particular event happening before or after another event of which the absolute date is well known.
For those researchers working in the field of human history, the chronology of events remains a major element of reflection. Archaeologists have access to various techniques for dating archaeological sites or the objects found on those sites. There are two main categories of dating methods in archaeology: Relative dating includes methods that rely on the analysis of comparative data or the context eg, geological, regional, cultural in which the object one wishes to date is found. This approach helps to order events chronologically but it does not provide the absolute age of an object expressed in years.

Three geologists have reported what they called the first "successful" direct dating of dinosaur bone. Will this new radioisotope dating or radiodating technique solve the problems that plagued older dating methods. If history is anything to go by, then the answer is no. The process generally used to date a fossil is circuitous and subject to differing interpretations. It has involved tracing the related sedimentary rock layer horizontally from the place where the fossil in question was found to a place where it is underlain or overlain or both by igneous rock. Igneous rock layers can supposedly be directly dated, so sedimentary layers sandwiched between them are interpreted to have been deposited in between the "ages" assigned to the igneous rocks. Where igneous rocks are absent, a fossil's "age" is determined by comparing the fossils of one location to those of another, and then comparing those comparisons to charts in books with age assignments provided on the pages. But in standard studies, no age assignment is ever accepted unless it conforms to the "millions of years" doctrine of evolutionary earth history. World Nuclear News pointed out one of the big problems with this dating approach by saying that the past "methods are far from perfect:.
