Prorichthofenia sp.
YPM.19122
Permian, Texas
| Richthofenia lived with its larger cone-shaped valve in the sediment. The smaller valve functioned like a lid. Its lifestyle is referred to as a “sediment sticker.” As you look into the cavity of Prorichthofenia, you can see the small lid-like free valve. |
