creekhunter Posted August 11, 2015 Posted August 11, 2015 How can you tell what time period the fossil is from? My son found this, (it looks like a turtle shell), it would be interesting to know what time period its from.
Raggedy Man Posted August 11, 2015 Posted August 11, 2015 I think what you have there is a slightly suggestive rock. 1 ...I'm back.

Sorry, but there are no turtle fossils in your area, as the bedrock formations there are Silurian or Ordovician in age - waaaayyyy before turtles were around. See this Generalized bedrock map of New York. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 IPFOTM -- MAY - 2024 _________________________________________________________________________________ "In every walk with nature one receives far more than he seeks."

Rob Russell Posted August 11, 2015 Posted August 11, 2015 I agree with Paul and Tim. It appears as though you have a glacial cobble. Welcome to the forum! 1 Finding my way through life; one fossil at a time.
Troodon Posted August 11, 2015 Posted August 11, 2015 Welcome to the forum. If it's a glacial cobble it still has a pretty good story behind it and is an interesting find. 1

My son found this, (it looks like a turtle shell), it would be interesting to know what time period its from. Welcome to TFF. There are few fossils that are exclusive to an exact time period. Although some can be quiet unique to a short period, and are used to date formations in which they are found. The best way to tell what time period a fossil is from is to research the age of the formation/area it came from. I have to agree with the others that the rock Your son found is just a cobble. Tony 1
Plax Posted August 11, 2015 Posted August 11, 2015 I see some hexagonal or octagonal shapes on the left side of pic one. Your rock could be a very worn paleozoic fossil of some sort. See if you can get a sharper pic. Some concretionary rocks can also have geometric shapes though. 1
