Abstract

Spines projecting from a trochospiral test of a spinose planktonic foraminifer are a single-crystal-like calcite that has a nanogranular texture containing microstrain and an organic envelope.

Discussions

• Let’s take a closer look at the spines of planktonic foraminifera. We find that crystals about 1 micrometer in size are arranged like this. This structure appears to underlie the mysterious mechanical [bsky, 1 points, 0 comments]
