Hone 2020 reviews anurognathid pterosaurs

Here’s a new paper from Dr. DWE Hone (2020). Quoting Hone’s own publicity sheet regarding the paper, “there’s not a huge amount to talk about here since as it’s a review, it doesn’t contain too much that’s new.” Even so, … Continue reading

Juvenile Rhamphorhynchus and flightless pterosaur abstracts
