Sure.. Why not.. after all, live frogs have been found entombed in coal..Why not a hammer, or a Rolex watch:
Curious History, Toads Entombed in Stone and Coal Found Alive After 100 Years... - http://bit.ly/14wRONp

The last photo is actually simply crinoid fossils.

Let me guess, they are using carbon dating to get the age? from coal ....

Yeah, Yeah, Yeah! Now, where's my remote control? Aha, there it is..........

Do you really believe they're 400 MILLION years old? How do the archeoalogists figure?
Yes, that they're very old, it's possible, but to believe these PhDs is to defy your own logical mind. They're funded by the Feds, and their own ambition and need for money, given them liberally, IF they say what the Feds want them to say. And the Feds, lie and lie and lie to us.
The ancient vedic scripture Srimad Bhagavatam states that dynasties of kings existed on this Earth hundreds of millions of years ago.
One scripture, the Brahma samhita, of which only one chapter out of a hundred chapters, the fifth chapter, survives today, is held to have been composed much much earlier than hundreds of millions of years ago, so various species of mankind have indeed occupied this planet for inconceivably longer than the government-funded 'archaeologists' are allowed to tell us, in case we start to have better aspirations, so we have to be kept believing that we have just crawled out of a blob of protoplasm. If we believe that, then they can carry on treating us as if we really have come from that source.
We are made in his image GOD.. Evil men will do all it takes to hold another human down.

You know, when I refer back to this page and check for replies, I keep seeing your rather strange comments after mine, and I just have to ask, what on earth are you writing about?
What is the virus you are talking about, as my computer never got one after downloading this page? And as for your second comment, don't you think it is a little out of place here? Why mess up the comments section to a really excellent article with total drivel?
I know, they say don't feed the troll, but you know, no one else asked, so I felt I really had to.
Check out the Seth material. We're not the first "civilization" to have lived on this planet. There have been a few before us who've died out for various reasons, to spring up again. According to Seth (take it as you will), the last civilization on this planet made it out into space and left this place. The universe (and I'm not talking about the physical universe) is vast, more vast than we can conceive of.

I agree with both mothman777 and Angela Graves. The epics from India talk about the 4 Yugas or Ages that span millenia. "According to Hindu cosmology, life in the universe is created and destroyed once every 4.1 to 8.2 billion years, . . . . A complete yuga cycle (consisiting of 4 Yugas) from a high Golden Age of enlightenment to a Dark Age and back again is said to be caused by the solar system's motion around another star." We are now in the KALI Yuga, the Iron Age of darkness, that is ending soon and we'll move into a lighter Age

These facts do not contradict that 'man is made in the image of God'. This belief is not the exclusive property of Christians. Hindus have always believed that human beings are a spark of the Divine (made in the image of God) and God or His representative descends as a human being to help mankind to ASCEND to Divinity. They are called Avatars. Jesus was also one such Divine Person who evolved to His Divinity in his life-time.
Let us not restrict humanity to a few thousand years or a few dogmas in this day and age!
The hammer in the limestone is easy to explain. It was probably a discarded or lost tool that was exposed to a constant flow of mineral rich dripping water. It would only take a few decades for the limestone to naturally encase the hammer. There is a skull in Cheddar Gorge that is almost completely encased in limestone yet there is a definite record of it being put there only 200 years ago. The stone cannot be carbon dated and looks for all intents to be natural. The artifacts found in coal is another story, I have no explanation.
The Voice of Russia and other Russian sources are reporting that a 300 million year old piece of aluminum machinery has been found in Vladivostok. Experts say a gear rail appears to be manufactured, and not the result of natural forces.
According to Yulia Zamanskaya, when a resident of Vladivostok was lighting the fire during a cold winter evening, he found a rail-shaped metal device which was pressed in one of the pieces of coal that the man used to heat his home. Mesmerized by his discovery, the responsible citizen decided to seek help from the scientists of Primorye region.
After the metal object was studied by the leading experts, the man was shocked to learn about the assumed age of his discovery. The metal artefact was supposedly 300 million years old, and the scientists suggested that it was not created by nature, but was rather manufactured by someone.
The question of who might have made an aluminum gear in the dawn of time remains unanswered.
The find was very much like a toothed metal rail, created artificially. It was like parts which are often used in microscopes, various technical and electronic devices.
Nowadays, finding a strange artifact in coal is a relatively frequent occurrence. The first discovery of this sort was made in 1851 when the workers in one of the Massachusetts mines extracted a zinc silver-incrusted vase from a block of coal, which dated all the way back to the Cambrian era, which was approximately 500 million years ago.
Sixty one years later, American scientists from Oklahoma discovered an iron pot which was pressed into a piece of coal aged 312 million years old.
Then, in 1974, an aluminum assembly part of unknown origin, was found in a sandstone quarry in Romania.
Reminiscent of a hammer or a support leg of a spacecraft, the piece dated back to the Jurassic era, and could not have been manufactured by a human.
All of these discoveries not only puzzled the experts but also undermined the most fundamental doctrines of modern science.
Another question that interests Russian scientists is whether the aluminum alloy is of Earthly origin. It is known from the study of meteorites that there exists extra-terrestrial aluminum-26 which subsequently breaks down to magnesium-26.
The presence of 2 percent of magnesium in the alloy might well point to the alien origin of the aluminum artefact. It could also be evidence of some past, unknown civilization on Earth. Nonetheless, further testing is needed to confirm this hypothesis.
It is the first such finding in coal made in Russia, according to anomaly researcher and biologist Valery Brier, who took microscopic samples of the aluminum for testing. Valery Brier performed X-ray diffraction analysis of the metal.
It showed very pure aluminum with microimpurities of magnesium of only 2-4 percent. Analysis was also conducted by Senior Fellow of the St. Petersburg Institute of Nuclear Physics Igor Okunev who confirmed the age of the material according to Natalia Ostrovsky
While exploring core samples (rock samples) that were raised from a 9-meter depth during the drilling of the seabed to support the bridge on a Russian island near Cape Nazimova, strange metal alloys were discovered that were "preserved" in the prehistoric sandstone (240 million years old).
The pieces of special alloys had an unusual composition, and were clearly not used in the drilling machinery.
Not so long ago in Russia a mechanical device was found in volcanic rock which was dated 400 million years before the current era (B.C.E)
It was found on the remote Kamchatka Peninsula, 150 miles from the village of Tigil, by archaeologists at the University of St. Petersburg, among some very strange fossils. The reliability of the finds has been certified.
According to archaeologist Yuri Golubev, the find amazed experts, as it was some kind of a machine.
