• Headers have the same data as in php-version
• Tests are implemented
• Documentation is written

Example for time unit: (abdounian) Abdounian - African Land Mammal Ages 55 Ma – 56 Ma AFLMA Age
Note:
At least references may not have title data and instead use only the description. Check php-version for how it is handled
