What was Convolosaurus?
Convolosaurus was a small plant-eating dinosaur from Early Cretaceous Texas. It is known from a rich collection of fossils around Proctor Lake. Many individuals, including young animals, make it useful for studying growth rather than relying on one isolated adult skeleton.
What makes the fossil distinctive?
The skull and skeleton place it among early ornithopod relatives. Differences between smaller and larger specimens can show how body proportions changed. Those differences also warn against naming every differently shaped juvenile as a separate species.
Where was it found and how was it named?
The fossil site was discovered in 1985, and Convolosaurus was formally named in 2019. The remains come from the Twin Mountains Formation. Some museum mounts combine bones from more than one specimen; such a composite can explain anatomy but is not a single animal found intact.
What can we infer, and what remains uncertain?
Its name refers to flocking because of the concentration of fossils. A bonebed is consistent with several explanations, including group living, repeated accumulation or transport. The arrangement of bones, sediment and ages of individuals helps distinguish these possibilities. The name records an interpretation worth testing, not a film of a herd moving together.
Does the name prove it lived in flocks?
No. A concentration of fossils motivates that hypothesis, but the way the bonebed formed must also be investigated.
How can you check the evidence?
The Paleobiology Database record catalogues Convolosaurus under Tenontosauridae. Its linked bibliography identifies this research starting point: K. A. Andrzejewski, D. A. Winkler, and L. L. Jacobs. 2019. A new basal ornithopod (Dinosauria: Ornithischia) from the Early Cretaceous of Texas. PLoS One 14(3):e0207935:1-44. Open the bibliographic record. A catalogue entry establishes the source trail; it does not independently verify every later illustration or behavioural claim.
Use the dated genus overview to follow the references behind the discovery and anatomy discussed above. When sources disagree, compare which specimen and rock layer each author studied. A reconstructed whole animal can combine original bones with comparisons to relatives; those two kinds of evidence should not be confused. The account above explains the particular limits that matter for Convolosaurus, rather than supplying unsupported size, speed or lifespan figures.
Read the image and keep exploring
A Convolosaurus mount presents a small ornithopod skeleton; display assembly should not be confused with a single intact burial. A displayed specimen or skeletal mount can include restored parts. Its appearance should be read alongside the original specimen description.

Quick answers
- Where have Convolosaurus fossils been found?
- The discoveries discussed here come from United States. Modern place names describe discovery locations, not a complete ancient geographic range.
- When did Convolosaurus live?
- It is placed in the Cretaceous period. See the discovery discussion for qualifications about the particular rock layers and dating.
- Where can I compare Convolosaurus with related dinosaurs?
- Follow the related field notes below. Comparisons explain shared anatomy; they do not imply that all the animals lived together.
