Correction to: Scientific Reports https://doi.org/10.1038/s41598-023-32057-x, published online 11 April 2023
The original version of this Article does not include evidence of registration in ZooBank within the work itself, as required by Art. 8.5.3 of the amended Code of the International Commission on Zoological Nomenclature (ICZN)1. Therefore, the newly proposed genus-group name Amanasaurus and species-group name A. nesbitti are not available. This issue has been corrected here and the new taxon name is now available.
The present publication has been registered in ZooBank with the LSID: urn:lsid:zoobank.org:pub:4D9DE818-3DFE-4300-90C4-D65E84DC12B2. The following ‘Zoobank’ and ‘Nomenclatural Acts’ subsections appear below, along with the modified ‘Systematic Paleontology’ section of the original Article2.

Amanasaurus nesbitti gen. et sp. nov.
[urn:lsid:zoobank.org:act:3A0099FE-DC2F-4714-B93E-92A9A1B5C28F (genus)]
[urn:lsid:zoobank.org:act:8250544F-1613–4857-A4ED-684BBB149CFE (species)]
Holotype
CAPPA/UFSM 0374, a proximal portion of a right femur.
Etymology
The genus combines the Tupi word “amana” (= rain) and the Greek “saurus” (= lizard), referring to the Carnian pluvial episode. The specific epithet honors Dr. Sterling J. Nesbitt, a prominent North American paleontologist, for his contribution and studies on silesaurs and Triassic archosaurs.
Type locality, age, and horizon
Pivetta site (29° 39′ 37″ S, 53° 25′ 51″ W), between the municipalities of Restinga Sêca and São João do Polêsine, Rio Grande do Sul, Brazil. Lower portion of the Candelária Sequence3 of the Santa Maria Supersequence4, Paraná Basin. The presence of the rhynchosaur Hyperodapedon places the Pivetta site within the Hyperodapedon Assemblage Zone5, which is considered mid to late Carnian (Late Triassic) in age according to high-precision U–Pb zircon geochronology that indicated a maximum age of 233.23 ± 0.73 Ma6.
Referred specimen
CAPPA/UFSM 0375, a distal portion of a left femur from an individual slightly larger than the holotype and excavated from the same locality.
Diagnosis
Amanasaurus nesbitti differs from all other known silesaurs with comparable material in (*local autapomorphies): posteromedial tuber of the femoral head reduced to absent; ventral margin of the anteromedial tuber exceeding the femoral head margin; presence of a fossa trochanterica; absence of a raised anterolateral scar; presence of a semi-circular scar on the posterodorsal surface of the femoral head*; cleft between the proximal tip of the anterior trochanter and the femoral shaft (see supplementary information of the original Article for a differential diagnosis).
Nomenclatural acts
This published work and the nomenclatural acts it contains have been registered in ZooBank, the online registration system for the International Code of Zoological Nomenclature. The ZooBank LSIDs (Life Science Identifiers) can be resolved and the associated information viewed through any standard web browser by appending the LSID to the prefix ‘http://zoobank.org/’. The LSID for this publication is: urn:lsid:zoobank.org:pub:4D9DE818-3DFE-4300-90C4-D65E84DC12B2.
