MEET THE ANIMAL
Meet Angimordella
Angimordella was a tiny beetle preserved in amber from northern Myanmar. Researchers named its species A. burmitina and measured the adult fossil at 4.25 millimeters long. Its body was strongly curved, with a head bent downward and sturdy hind legs. This measurement belongs to one fossil, rather than a size range for the whole genus. Amber protected small details that would often be lost in rock fossils. [D1]
A Nanjing research-team account describes a closer look at pollen near the beetle. Scientists used confocal microscopy to reveal grains that were difficult to see among its body hairs. Studying these small structures made the specimen an important clue in investigations of Cretaceous plant–insect relationships. Finding pollen touching an insect is useful evidence, but explaining what that insect was doing requires more than simply recognizing the grains. [D3]
The interpretation changed when researchers examined the specimen again in 2026. They supported placing Angimordella in an extinct stem branch of the mordellid beetles. Its mouthparts do not clearly demonstrate the specialized pollen-feeding adaptations proposed earlier. It may have contacted plants in a more general way. The specimen therefore preserves a real pollen association, while its exact feeding role and degree of pollination specialization remain uncertain. [D2]

How to read the evidence
Source supported identifies a description documented by the cited source. Inferred marks a reconstruction or functional estimate. Debated marks competing interpretations. Not established means the sources reviewed for this dossier do not support a firm conclusion; it does not mean a behavior never occurred.
A size reference is an estimate, not a population range. Nesting evidence does not by itself establish courtship, mate choice, or lifelong pairing.
Body mass
Not establishedNot established here
No body-mass estimate is reported for the type. [D1]
Diet
Not establishedNot established here
Pollen contact is preserved, but the reassessment finds no unequivocal specialized pollen-feeding adaptation. [D2]
Habitat
InferredResin-producing woodland inferred
Kachin amber gives burial context; exact living perch and host plant remain uncertain. [D3]
Movement
InferredWalking and flight inferred
Legs and beetle wings support these capabilities; speeds and characteristic escape movements are unmeasured. [D1]
Distinctive anatomy
Source supportedConvex body and stout hind legs
The adult has serrate antennae, a strongly declined head and a very short pygidium. [D1]
Reproduction & life together
Reproduction
Not establishedNot established here
The reviewed original describes an adult, without attributable eggs or young. [D1]
Courtship
Not establishedNot established here
No mating sequence or mate-choice evidence is supplied in the reviewed description. [D1]
Social behavior
Not establishedNot established here
A pollen-associated amber inclusion does not establish colonies or cooperation. [D3]

THE STORY IN THE FOSSILS
Pollen between the hairs
The institutional discovery account explains how confocal microscopy revealed pollen among body hairs. That close association is a fossil observation; its ecological meaning needs separate interpretation. [3]
A note on scale and time
The dossier identifies the scope of each reference estimate. A mount, an individual fossil and a species-wide adult range are different measurements. Comparison metrics remain unavailable where adult scope has not been established. Unknown does not mean zero.
