Silverstri (1912) described two genera and eight species of Machilidae or Machiloidae incertae sedis from Baltic amber (35-40 Myr). In Cretaceous Myanmar amber (burmite: -99 Myr) one preserved Machilidae plus five undetermined specimens were reported but with no details by Grimaldi et al. (2002). In Dominican amber (20-25 Myr) only Neomachilellus (Praeneomachilellus) dominicanus (Sturm & Poinar 1997: Meinertellidae) has been found.
