Source-derived summary

Guanlong is an extinct genus of proceratosaurid tyrannosauroid dinosaur from the Late Jurassic (Oxfordian) Shishugou Formation of China. It was first described in 2006 by Xu Xing and colleagues, who found it to represent a new taxon related to Tyrannosaurus. Two individuals are currently known, consisting of a partially complete adult and a nearly complete juvenile.

Editorial summary

“Guanlong” enters the record as extinct genus of dinosaur. Crown Archives preserves that source wording while asking what Guanlong, Extinct and genus can confirm, complicate or overturn.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current lead gives the account dated anchors—2006—that can be checked directly. The selected authority fields contribute no independent date. Its strongest next move is a source search built around Guanlong, Extinct and genus.
Editorial analysis

Why this record matters

“Guanlong” is worth following because a concise public description often conceals a longer documentary argument. Here, Guanlong, Extinct and genus provides the most credible route into that argument.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Sep 12, 2026. The first chronological checks are 2006.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
