The National SAFEKIDS Campaign recommends that no child under the age of 12 be left at home alone. However, consider a child's age and maturity level. For example, if a child is extremely impulsive, it might be best to wait until he or she is older than 12.
Did people and dinosaurs live at the same time? No! After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.
1 Some types of dinosaurs ate only meat (carnivores), some ate only plants (herbivores), and some ate both plants and meats (omnivores). 2  Many people incorrectly assume that all the dinosaurs lived together at the same time. 3  This was not the case.
