My horse trainer told me that horses know what is good for them and what is bad for them, if he eats it and nothing happens to him then he's fine and he can eat it, but if he refuses it might mean that he doesn't like it or he thinks it's bad for him. Page 1 of 3 1 2 3 Last.
1 Measuring the length of long bones can give an estimate of age for children, but this technique is useful only until bones have stopped growing. 2  The tibia completes growth at about age 16 or 17 in girls, and 18 or 19 in boys.he ends (epiphyses) and bony shafts (diaphyses) of long bones form separately in the womb. At birth, the ends of the long bones are mainly cartilage, with centers of bone beginning to form inside.
Since then, scientists have found hundreds of fossilized Megalodon teeth and spinal segments known as centra. Because a sharkâs skeleton is made up of cartilage, which dissolves quickly in ocean water, these are the only Megalodon remains that have survived over millions of years. Scientists are able to learn a lot about Megalodon from these fragments. For example, experts can determine a Megalodonâs age at death by examining the centra. Each centra contains growth rings, sort of like a tree. By counting the rings, their color, and how far apart they are, scientists are even able to determine a Megalodonâs growth rate.
