Deinocroton
extinct genus of tick
Deinocroton is an extinct genus of tick. It is known from four species found in Burmese amber, dating to the earliest part of the Cenomanian stage of the Late Cretaceous, around 99 million years ago.
Taxonomy
Four species have been named, including the type species D. draculi, D. copia, D. bicornis and D. lacrimus all from Burmese amber, which dates to the late Albian-early Cenomanian stages of the Cretaceous period, around 100 million years ago. The genus is suggested to be more closely related to Nuttalliella than to the two major living families of ticks, which is supported by the anatomy of its leg joints. While originally placed in its own family Deinocrotonidae, a 2024 study suggested that it should be placed into Nuttalliellidae, along with Nuttalliella and the extinct genus Legionaris also known from Burmese amber.

Etymology
The name of the genus Deinocroton is composed of two words from the ancient Greek "deinos", "terrible", and "krotṓn", "krotṓn", "tick". The name of the species draculi refers to the vampire Count Dracula from the epistolary novel Dracula by British writer Bram Stoker.
Description
Deinocroton is distinguished from other ticks by a suite of characters relating to the structure of its integument, the morphology of the palps, and the preanal groove shape. The surface of the body is densely pitted with deep pits, and eyes are absent.
This brief starts where responsible research should: with the source description of “Deinocroton” as extinct genus of tick. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as extinct genus of tick. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 11, 2026. The linked authority identifier is Q50177259. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2024 and 2022.
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
