Hillsborough Shell Stamped is a Late Woodland pottery type from the Tampa Bay vicinity. According to Willey 1949:441, the type has "Similarities noted to Ruskin Dentate Stamped, a companion type".

As described by Willey 1949:440:

Definition as a type: From Tampa Bay vicinity, this paper

Ware characteristics: Probably a colided ware. Sand-tempered. Usually granular and compact with only occasional contortions and laminations. Core is black, gray, or dark brown. Surfaces often buff. Interior smoothing excells exterior surface treatment. Thickness averages 8 to 9 mm.

Decoration:

Technique: Impression of the edge of a scallop shell or the back of a scallop shell onto the soft, unfired surface of vessel.

Design: Wide-spaced application of back of shell. Each unit application has 3 or 4 bars, each bar being about 1 mm. wide and 8 mm. long. Between bars are rows of tiny dots which are a part of the same impression. When edge of scallop shell is used, the applications are close-spaced, giving the effect of rows of small, round dots, comma-shaped dots, or triangular dots. There is considerable overlapping of these rows of dots, and the rows have no particular orientation on the vessel. (Pl. 38, b-g.)

Distribution: Covers most or all of exterior vessel.

Form: Deep, open bowls and jars or bowls with incurved walls. Very small, rounded exterior rim folds are sometimes used. Lips are round-pointed. There are some triangular rim projections.

Geographical range of type: Mostly from Tampa Bay vicinity.

Chronological position of type: Probably confined to Weeden Island II.

Relationships of type: Similarities noted to Ruskin Dentate Stamped, a companion type. Vaguely reminiscent of Crooks Stamped, a shell-stamped type of the Marksville Period of southern Louisana (Ford and Willey, 1940).
