5. Weigh the Turtle
Use a kitchen or postage scale to weigh the turtle. The size must be correct to inside 1 gram or 0.05 ounces. Report the burden in grams or ounces.
| Measurement | System |
|—|—|
| Carapace Size | CL = Distance from entrance to again of carapace |

| Plastron Size | PL = Distance from entrance to again of plastron |
| Plastron Width | PW = Distance throughout widest level of plastron |

To rely the scute rings, you will have to look at the turtle’s shell beneath a shiny mild. The rings are most seen on the scutes on the highest of the shell (carapace). Rely the variety of rings on a number of totally different scutes and take a median to get a extra correct estimate.
Measuring the Carapace Size
The size of a field turtle’s carapace (prime shell) will also be used to estimate its age. The connection between carapace size and age will not be as exact as counting scute rings, however it may present a basic estimate.
Measuring the Plastron Size
The size of a field turtle’s plastron (backside shell) will also be used to estimate its age. The connection between plastron size and age will not be as exact as counting scute rings, however it may present a basic estimate.
Evaluating to a Reference Chart
There are a number of reference charts accessible that present an approximate age vary primarily based on the size of a field turtle’s carapace or plastron. These charts should not at all times correct, however they’ll present a basic estimate.
Further Components to Take into account
Along with the methods described above, there are a number of different components that may have an effect on the accuracy of age willpower, together with:
