Typefaces with thick serifs are usually called Slab Serifs. The earliest examples were called Antiques or Egyptians in the 19th century and many still refer to them as Egyptians. These typefaces can have slab serifs that are bracketed or unbracketed. They frequently have names that reference Egypt such as Giza. Typefaces with geometric proportions that have unbracketed slab serifs are often called Square Serifs. Examples are Stymie and Memphis. Unbracketed slab serifs can also be found on "humanist" typefaces such as Serifa and PMN Caecilia.
