Aspidoceratidae
The Aspidoceratidae comprise a family of middle and upper Jurassic ammonites that make up part of the superfamily Perisphinctoidea, characterized by evolute shells, commonly stocky, that tend to develop tubercles.

gollark: Intel decided to add tons of cores to their laptops without (allegedly) increasing the TDP, so clocks are bad.
gollark: Well, the most powerful one is the last one, since it appears to have a decent processor and GTX 1660, but obviously other stuff matters.
gollark: It has an actual dedicated GPU, might be better for gaming.
gollark: If you aren't doing heavy gaming, then I think basically anything with a decently sized SSD, good screen (1080p+, IPS), enough RAM, recent i5/R5 and up, and whatever other stuff you want should be okay.
gollark: Um, anyway, for gaming you probably want something with a dedicated GPU if possible.
