description: Theiler stages (TS) define mouse development by a set of morphological
  criteria ([Theiler, 1989](https://doi.org/10.1007/978-3-642-88418-4)). This staging
  scheme is used because embryos at the same gestational age can have developed at
  different rates and therefore exhibit different morphological characteristics. Theiler
  stages may in some cases correspond to a single gestation age, but more often cover
  a range of ages. (from [https://www.informatics.jax.org/glossary/theiler](https://www.informatics.jax.org/glossary/theiler))
