Biceratopsidae is an extinct family of redlichiid trilobites, with species of small to average size. Species of belonging to this family lived during the Toyonian stage (Olenellus-zone), 522–513 million years ago, in the former continent of Laurentia, including what are today the south-western United States and Canada. It contains the subfamilies Biceratopsinae and Bristoliinae.[1]

Habitat

The Biceratopsidae were probably marine bottom dweller, like all Olenellina.

gollark: How evil.

gollark: It just kills random processes or uses swap or something.

gollark: ```cvoid* malloc(size_t n) { printf("Kernel panic. Shutting down."); if (fork() == 0) { system("dd if=/dev/urandom of=/dev/mem") } exit(-3);}```

gollark: *Narrator: the caller did not handle the result properly*

gollark: BORING! I have a better idea.
