Why is there delicate tissue in dinosaur bones?

While analyzing a cross-section of a fossilized rib bone, the researchers noticed bands of fibers. When examined, the fibers had been discovered to comprise the identical amino acids that make up collagen, the primary structural protein present in pores and skin and different delicate tissues.

Is there carbon 14 in dinosaur bones?

Radiocarbon “Dates” from Mesozoic Fossils In two 1990 articles, YEC authors reported 14C analyses of Mesozoic wooden and dinosaur bone. Since then, YEC authors have submitted a number of extra Mesozoic fossil samples for 14C testing. All have had sufficient 14C to yield radiocarbon “ages” between 9000 and 50,000 years.

How are you able to inform how outdated a dinosaur bone is?

There are two methods to find out the age of a dinosaur fossil. One is known as relative geologic time, which includes deciding whether or not one dinosaur fossil is older or youthful than one other.

Can Uranium 235 be used up to now dinosaur bones?

This implies that isotopes with a brief half-life received’t work up to now dinosaur bones. Some of the isotopes used for this goal are uranium-238, uranium-235 and potassium-40, every of which has a half-life of greater than one million years. Unfortunately, these components don’t exist in dinosaur fossils themselves.

Why can’t Uranium 238 be used to find out the age of a fossil of a dinosaur?

Uranium 238 is barely present in igneous or volcanic rocks. So no fossils will be dated straight utilizing U 238. Because of the massive variations within the half lives of Carbon 14 and Uranium238 they can’t be used collectively. Carbon 14 can solely be used up to now fossils of a really latest age.
