You can find the cache at N 33° 34.ABC W 117° 42.DEF. First stage is at the above coordinates.
A= The approximate million years ago that the exhibit were trying to recreate. Add the 2 numbers together.
B= The last digit in the feet that it grew and subtract the last digit in the year that the first of this species was found in.
C= The number mining chisels you see in the three pictures and subtract it by the number you see in the middle picture. Hint: Yes they all have at least one chisel in the picture.
Ok, now head over to N 33° 34.062 W 117° 42.543 for the next set of needed numbers.
D= The approximate million years that this species lived ago. Add the numbers together and then divided by its estimated length without the 0. This should leave you with one digit. Then add one to it.
E= The teeth length then subtract the number of real teeth on the plaque in the display. Not the artist drawing, the real one.
F= The artist picture of the shark eating 3 fish. The largest font number that the shark seems to be swimming to. Subtract all the digits from the number. If you get a negative number, then you did it wrong.
Now, go get the cache. It is an easy park and grab if you look in the right place. Please rehide as found. You are looking for a non camoed bison tube.
Checksum for the values of A through F = 18/p>
