You can give them to Nook whether they are examined or not. It's just that if they are not examined then he won't pay you for them, instead he will just take them off you. So if I were you, I would give them to Blathers then sell them to Nook.
The preserved remains of animals of evidence of their existence are Fossils Fosssils that provide evidence about the past are called trace fossils.
thay cost 2000
Index fossils (also known as guide fossils, indicator fossils or zone fossils).
Mosasaur fossils are fossils of the prehistoric sea monster called Mosasaurus.
Fossils can be any Kingdom. We have found fossils of plants, worms, animals plus many others.
Examined. He won't blow the whistle if Blathers does not exam them.
You just have to catch rare fish, bugs, and dig up fossils and let Blathers examan them and then sell them to Tom Nook.
Blathers the owl is a bright one who runs the museum pretty much by himself. He can check fossils for you and accept any donations. He holds an index of all the items in the museum (there's fish, bug, painting and dinosaur bone sections). Blathers is very smart, but when it comes to bugs he is extremely squeamish. Blathers cannot stand bugs, so if you give him one to display prepare for a squeal or two.
on animal crossing wild world you will have a museum,tom nooks,able sisters,town hall and a main gate if you go to the museum there will be a owl sanding there (if you have already talked to him he is awake if not he is asleep) he is blathers you donate fossils,fish and bugs to him if you keep talking to him over and over again you will beome freinds with him!
First you have to get the museum to check it first(Blathers the owl will) and then you can give it to a friend that wants it. Be sure that you don't accidentally donate it to the museum during this process though.
If you pay your mortgage Nook's Shop will upgradeIf you donate lots of things such as Fossils, Fish, Paintings and Insects animals will go to your museum and Blathers will stay awake
Like all fossils, they are buried in the ground, underneath the little star. It's impossible to predict which fossil you will get, as it is random. You just have to keep taking fossils to Blathers, and eventually you'll find it. :)
You dig for fossils where there is a brown X on the ground.
The only thing that i have heard is when you give Tom Nook 50 fossils ( that haven't been checked by Blathers) he will blow a whistle and then someone will take you to ACWW island.
Keep digging fossils up and eventually you'll get them all.
Fossils are under ground at random points in the day or night.
There is no such code.
