‘Oculudentavis’ #2 is not Oculudentavis

Bolet et al. 2020 bring us specimen #2 of ‘Oculudentavis’.“Here we describe a more complete, specimen [GRS-Ref-286278, Fig. 1] that demonstrates Oculudentavis is actually a bizarre lizard of uncertain position. The new interpretation and phylogenetic placement highlights a rare case of … Continue reading

AMNH pterosaur video: due for an Oculudentavis-type retraction

Recently (March 2020 to July 2020) Xing et al. 2020 agreed to retract their paper on Oculudentavis because they said it was a bird and it turned out to be a lepidosaur. Also recently (July 31, 2020) the American Museum … Continue reading

Oculudentavis reply: bird? lizard? or option #3?

O’Connor et al. 2020 are not giving up without a fight.  Now they are arguing against a published objection (Li et al. 2020) to their interpretation of Oculudentavis as a strange tiny bird encased in Early Cretaceous Burmese amber. Citation … Continue reading

Oculudentavis in more incredible detail! (thanks to Li et al. 2020)

Li et al. 2020 bring us higher resolution scans of the putative tiny toothed ‘bird’ (according to Xing et al. 2020) Oculudentavis (Fig. 1). Following a trend started here a week ago, Li et al. support a generalized lepidosaur interpretation, … Continue reading

Did Oculudentavis have an antorbital fenestra?

Some say: Yes. Others say: No. You decide.  Here are two CT scans (Figs. 1, 2), one from the left and the other from the right with overlays interpretating skull sutures, enlarged from the previous presentation. Now, perhaps, you can … Continue reading

You heard it here first: Others also doubt the theropod affinities of Oculudentavis

The now famous tiny skull in amber, Oculudentavis,  (Fig. 1; Xing et al. 2020) continues as a topic of conversation following its online publication in Nature and two previous PH posts here and here. Several workers have also thrown cold … Continue reading

Oculudentavis: First 3D skull of pterosaur precursor discovered with skin!!!

That could have been the spectacular headline circulating ’round the world now about Oculudentavis (Fig. 1, Xing et al. 2020), the tiny (1.4cm) skull found in Early Cretaceous Burmese amber. “Smallest Mesozoic dinosaur skull discovered” is also pretty exciting, but … Continue reading

Oculudentavis: not a tiny bird or dinosaur. It’s a tiny cosesaur lepidosaur.

I never thought the tiny Middle Triassic pterosaur ancestor, Cosesaurus (Fig. 2, 4) would ever be joined by an Early Cretaceous sister taxon that was even smaller. Yesterday the impossible happened when the editors of Nature published a description of … Continue reading
