Tristichopteridae is a family of tetrapodomorphs from the Middle and Late Devonian. Some of them share some of the features of the elpistostegalians. The most well-known is probably Eusthenopteron.
A classic notion is that Eusthenopteron was able to crawl onto land using its fins. However, no evidence believes this and is believed by many to be false.
